60 Years of the Loeb-Sourirajan Membrane: Principles, New Materials, Modelling, Characterization and Applications bring forth theoretical advances, novel characterization techniques, materials development, advanced treatment processes, and emerging applications of membrane-based technologies. The trigger for writing this book is the 2020, 60th anniversary of the first asymmetric polymeric membrane invented by Dr. Sidney Loeb and Dr. Srinivasa Sourirajan (University of California, Los Angeles, USA) on the breakthrough discovery of the semipermeable membrane for seawater desalination. The book places emphasis on the advances of organic and inorganic membranes in different fields, covering not only the primary application of membranes for water and wastewater treatment but also other applications dealing with energy conversion and storage, organic solvent purification, gas separation, and biomedical processes.
The removal of organosulphur compounds (ORS) from diesel fuel is an important aspect of Jordanian's effort to reduce air pollution. Currently, the total sulphur content in Jordanian diesel fuel is 12000ppmw (1.2%, wt/wt), but Jordanian government has recently introduced new restrictions that will reduce this level gradually to internationally acceptable levels. The zeolitic tuff (ZT), from Tlul Al-Shahba region, was characterised using various analytical techniques. It was found that the Freundlich model fitted the adsorption isotherms more accurately than the Langmuir model; indicating that the ZT had a heterogeneous surface. The Langmuir adsorption capacity values for the three particle size ranges (100-200), (300-400), and (500-600) _mwere 7.15, 6.32, and 5.52 mg/g and the column capacities were 4.45, 2.57, and 1.92 mg/g, respectively. The spent ZT was regenerated by washing with n-heptane with an efficiency of 81.5%. Two adsorption mechanisms were investigated. One is that the interaction of thiophene with the Bronsted site of the ZT through S atoms; the other is via C-S bond cleavage in thiophene-derived carbocations to form unsaturated fragments on the Bronsted acid sites."
