Natural Water Remediation: Chemistry and Technology considers topics such as metal ion solubility controls, pH, carbonate equilibria, adsorption reactions, redox reactions and the kinetics of oxygenation reactions that occur in natural water environments. The book begins with the fundamentals of acid-base and redox chemistry to provide a better understanding of the natural system. Other sections cover the relationships among environmental factors and natural water (including biochemical factors, hydrologic cycles and sources of solutes in the atmosphere). Chemical thermodynamic models, as applied to natural water, are then discussed in detail. Final sections cover self-contained applications concerning composition, quality measurement and analyses for river, lake, reservoir and groundwater sampling.

Potentiometric Water Analysis Second Edition Derek Midgley and Kenneth Torrance, National Power plc, Technology and Environmental Centre, Leatherhead, Surrey, UK This volume is a thoroughly revised and updated version of the very successful first edition. It provides, in one single volume, a comprehensive survey of the theoretical and practical aspects of potentiometry and ion-selective electrodes applied to the analysis of water. The first part of the book describes the basic theory of electrodes, the statistical treatment of results, titrimetric methods and general guidance on procedures. Useful information is given on the types of electrodes available, together with the apparatus required for laboratory and industrial use. For this second edition, the authors include details on microprocessor-based instruments, new electrodes and techniques that have recently been developed, as well as updating the variations on established procedures and their performance characteristics. The second part of the book gives detailed analytical methods for identifying a variety of determinands. Worked examples with discussions of sources of error and likely accuracy are also included. The book is designed to give sufficiently detailed procedures so that the reader can use the methods without recourse to the primary literature. With its emphasis on the practical aspects of potentiometric water analysis, this book will be a valuable tool for analysts working in the field.

This volume compiles and discusses the fundamental and multidisciplinary knowledge on adsorption and separation processes using zeolites as adsorbents. Over the last decade, a large amount of research has been carried out for the development of zeolites as adsorbents. However, there is still a growing interest to increase the understanding of such selective adsorbents. Therefore, synthesis strategies and new approaches for developing new selective zeolite adsorbents for gas separation are presented in the first chapter. In addition, a chapter focused on adsorption characterization techniques of microporous materials is included. This will be helpful for advanced readers, since the new IUPAC recommendations for microporous characterization are not still widely employed by the zeolite community. Experimental and theoretical aspects of economically and environmentally relevant separations, which have been successfully carried out with zeolites, are discussed in detail in subsequent chapters. Finally, industrial zeolite based adsorption and separation processes as well as current perspectives for new zeolite based separations, and improvements of current technologies are presented.

Chemometrics in Spectroscopy, Second Edition, provides the reader with the methodology crucial to apply chemometrics to real world data. It allows scientists using spectroscopic instruments to find explanations and solutions to their problems when they are confronted with unexpected and unexplained results. Unlike other books on these topics, it explains the root causes of the phenomena that lead to these results. While books on NIR spectroscopy sometimes cover basic chemometrics, they do not mention many of the advanced topics this book discusses. In addition, traditional chemometrics books do not cover spectroscopy to the point of understanding the basis for the underlying phenomena. The second edition has been expanded with 50% more content covering advances in the field that have occurred in the last 10 years, including calibration transfer, units of measure in spectroscopy, principal components, clinical data reporting, classical least squares, regression models, spectral transfer, and more.

This book aims to give state of the art in several domains of cultural heritage in which Nanosciences allow fundamental breakthrough. The first part of the book concerns nanostructured materials in ancient artifacts. Understanding their nature and formation processes bring new insight in the apprehension of technical level of ancient societies but can also inspire the design of new materials. The second part is dedicated to the understanding of materials. This crucial issue in material science today, for cultural heritage, needs to perform specific characterization techniques and technologies, but also to create tailored analytical strategies. Part three presents new methods, processes and materials at nano levels that can bring innovative solutions to conservation and restoration issues, linked with the understanding of the alteration processes involved at different scales.

Over-pumping of aquifers is a worldwide problem, mainly caused by agricultural water use. Among its consequences are the falling dry of streams and wetlands, soil subsidence, die-off of phreatophytic vegetation, saline water intrusion, increased pumping cost and loss of storage needed for drought relief. Stopping or reversing the trend requires management interventions. The North China Plain serves as an example. A management system is set up for a typical county. It contains three components: monitoring, decision support based on modelling, and implementation in the field. Besides all monitoring data, the decision support module contains an irrigation calculator, a box model, and a distributed groundwater model to project the outcomes of different water allocation scenarios. In view of grain security, a solution combines an adaptation of the cropping system with imports of surface water from the South. The Open Access book does not only describe the problem and the path to its solution. It also gives access to nine manuals concerning methods used. They include computer programs and the game Save the Water. The Chinese experience should be of considerable interest to other regions in the world which suffer from over-pumping of aquifers.

Chiral Analysis: Advances in Spectroscopy, Chromatography and Emerging Methods, Second Edition covers an important area of analytical chemistry of relevance to a wide variety of scientific professionals, including chemistry graduate students, analytical chemists, organic chemists, professionals in the pharmaceutical industry, and others with an interest in chirality and chiral analysis. This thoroughly revised second edition covers several new, important areas of chiral analysis that have emerged since the first edition. Three of the new methods provide higher sensitivity than can be realized with the current methods and are expected to become mainstream applications: cavity based methods offer vastly higher sensitivity than conventional polarimetric methods, microwave chiral detection provides unsurpassed sensitivity for identifying diastereomers, and the rotating electric field method offers a competing new approach for the separation of enantiomers. Another topic, chirality in extraterrestrial life, has not been discussed in any other book and is important for understanding the origin of life.

In this thesis Johanna Bruckner reports the discovery of the lyotropic counterpart of the thermotropic SmC* phase, which has become famous as the only spontaneously polarized, ferroelectric fluid in nature. By means of polarizing optical microscopy, X-ray diffraction and electro-optic experiments she firmly establishes aspects of the structure of the novel lyotropic liquid crystalline phase and elucidates its fascinating properties, among them a pronounced polar electro-optic effect, analogous to the ferroelectric switching of its thermotropic counterpart. The helical ground state of the mesophase raises the fundamental question of how chiral interactions are "communicated" across layers of more or less disordered and achiral solvent molecules which are located between adjacent bi-layers of the chiral amphiphile molecules. This thesis bridges an important gap between thermotropic and lyotropic liquid crystals and pioneers a new field of liquid crystal research.

This book explains how the partial differential equations (pdes) in electroanalytical chemistry can be solved numerically. It guides the reader through the topic in a very didactic way, by first introducing and discussing the basic equations along with some model systems as test cases systematically. Then it outlines basic numerical approximations for derivatives and techniques for the numerical solution of ordinary differential equations. Finally, more complicated methods for approaching the pdes are derived. The authors describe major implicit methods in detail and show how to handle homogeneous chemical reactions, even including coupled and nonlinear cases. On this basis, more advanced techniques are briefly sketched and some of the commercially available programs are discussed. In this way the reader is systematically guided and can learn the tools for approaching his own electrochemical simulation problems. This new fourth edition has been carefully revised, updated and extended compared to the previous edition (Lecture Notes in Physics Vol. 666). It contains new material describing migration effects, as well as arrays of ultramicroelectrodes. It is thus the most comprehensive and didactic introduction to the topic of electrochemical simulation.

The thesis provides the necessary experimental and analytical tools to unambiguously observe the atomically resolved chemical reactions. A great challenge of modern science has been to directly observe atomic motions during structural transitions, and while this was first achieved through a major advance in electron source brightness, the information content was still limited and new methods for image reconstruction using femtosecond electron diffraction methods were needed. One particular challenge lay in reconciling the innumerable possible nuclear configurations with the observation of chemical reaction mechanisms that reproducibly give the same kind of chemistry for large classes of molecules. The author shows that there is a simple solution that occurs during barrier crossing in which the highly anharmonic potential at that point in nuclear rearrangements couples high- and low-frequency vibrational modes to give highly localized nuclear motions, reducing hundreds of potential degrees of freedom to just a few key modes. Specific examples are given in this thesis, including two photoinduced phase transitions in an organic system, a ring closure reaction, and two direct observations of nuclear reorganization driven by spin transitions. The emerging field of structural dynamics promises to change the way we think about the physics of chemistry and this thesis provides tools to make it happen.

Using keywords of modern Analytical Chemistry, it constructs a teaching message accessible to the beginner, with emphasis on relations between these keywords to ensure consistency in the teaching contents of the book. Practical exercises, 450 questions for students, and 27 interactive seminars are used as vehicles for expounding a large number of examples in order to clarify and consolidate the text and facilitate its comprehension.

More than one and a half decades have passed since the last book was published describing developments in the analytical chemistry of synthetic colorants. In the intervening period, the scope and technical capabilities of instrumentation for analysing dyes and pigments has significantly expanded. It is now possible to rapidly resolve a number of problems whose solutions were previously either unattainable or very difficult to achieve. For instance, the unambiguous assignment of all the signals in the proton NMR spectrum of a trisazo direct dye, and the confirmation of the molecular weight of involatile, and, in particular, sulphonated dyes, without derivatisation, are now routine analytical techniques in many laboratories today. In addition, it is now possible to record the NMR spectrum of a dye molecule on less than 1 mg of material, and we are no longer limited to solution spectra, since solid samples can now be routinely analysed in NMR experiments. Whilst not attempting to be all encompassing, this volume is intended to bridge the gap between what was covered in the earlier work edited by Professor Venkataraman and the developments which have since ensued in some key areas. It provides important updates in X-ray crystallography, proton NMR, IR spectroscopy and mass spectrometry, and additionally covers topics such as ESR, micro spectrophotometry and emission spectroscopy.

This book presents innovative research on soil nitrogen cycling and nitrate leaching with a view to improving soil management and fertiliser nitrogen use efficiency and reducing nitrogen leaching losses. In this regard, nitrogen-15 (15N)-labelled fertiliser was used as a biochemical and physical stable isotope tracer in laboratory and field experiments. The major outcome of the research was the development, validation and application of a new compound-specific amino acid 15N stable isotope probing method for assessing the assimilation of fertiliser nitrogen by soil microbial biomass. The novelty of the method lies in its tracing of incorporated nitrogen into newly biosynthesised microbial protein in time-course experiments using gas chromatography-combustion-isotope ratio mass spectrometry. The approach provides previously unattainable insights into the microbial processing of different nitrogen fertilisers in different soils. Further, it identifies the mechanistic link between molecular-scale processes and observations of field-scale fertiliser nitrogen immobilisation studies. The method and the results presented here will have far-reaching implications for the development of enhanced recommendations concerning farm-based soil management practices for increasing soil productivity and reducing nitrogen losses, which is essential to minimising environmental impacts.
