An Introduction to Aluminosilicates first reviews the main advances
in methods of obtaining synthetic montmorillonite for environmental
and biomedical areas. The perspectives and main challenges in the
application of these materials is critically analyzed. The authors
next study Polyhydroxy metal complexes of Al, Fe, Zr, Cr and Ti
(inorganic pillarizing agents) for the synthesis of pillared clays.
Information is provided on the possibility of using amorphous
aluminosilicates as a modifying additive in the formulation of
cement-based dry building mixtures. The physicochemical properties
of the additive are considered, and the results of XRD and DTA
analyzes are presented. The authors investigate the molecular
orientation and surface morphology of organized molecular films
with regard to solidastate structures for organo-modified
aluminosilicates by a surface pressure-area isotherm, in-plane and
out-of plane X-ray diffraction, and atomic force microscopy. A new
method for the synthesis of amorphous mesoporous aluminosilicates
with acidic properties and a narrow pore size distribution in the
range of 2-7 nm is also explored. The urease immobilization of
composite adsorbents polyacrylamideabentonite,
polyacrylamideachitosan, and polyacrylamideachitosanabentonite is
assessed, produced from polyacrylamide as a hydrogel, bentonite as
an aluminosilicate mineral, and chitosan as a polysaccharide.
Following this, the authors provide a brief overview of literature
data where crystalline aluminosilicates have been utilized for the
capture and immobilization of radionuclides. The physiochemical
properties of as-synthesized layered aluminosilicate are
characterized by small angle PXRD, FTIR, porosity studies, thermal
studies, 27Al MAS NMR, and morphological studies. Subsequently,
this compilation addresses the way in which magnetic nanoparticles
have proven to be frequently occurring building blocks for hybrid
structure construction and, moreover, have shown innovative
prospects as multifunctional adsorbents. Modern methods for the
synthesis of highly dispersed micro- and micromesoporous mordenite
with a high degree of crystallinity, as well as high crystallinity
mordenite with a hierarchical porous structure, methods for
modifying the mentioned crystalline aluminosilicates as a result of
postsynthetic treatments, and modern adsorption and catalytic
systems based on them are described. Next, the high activity and
selectivity of high crystallinity zeolite Y with a hierarchical
porous structure in the synthesis of practically important
oligomers of various unsaturated compounds is established. The
authors highlight that the aluminosilicate present in kaolin may
also be used in the production of zeolitic materials, and some
details of this application are explained. The adsorptive features
of PAAm-Ch-Z for Th4+ are investigated in view of its dependency on
pH, concentration, time, temperature and ionic strength. The
parameters derived from the compatibility of experimentally
obtained data to Langmuir, Freundlich and Dubinin-Radushkevich, van
t'Hoff, pseudo frist-/second-order and Weber Morris models are
utilized in the evaluation of adsorption and its thermodynamics and
kinetics. Lastly, the authors consider a possible mechanism for the
generation of an acetyl-zeolite intermediate via transfer from
different acetyl donors through theoretical studies using a cluster
model of H-ZSM-5 zeolite designed by three TO4 tetrahedral units.
