Discussion of a Master’s Thesis
The Department of Chemistry at the College of Education for Pure Sciences at the University of Karbala discussed a master’s thesis entitled (Water purification from carbonate and phosphate ions using zinc/aluminum dihydroxide Zn/AI-LDH nanolayers), for the student (Fares Abdul Amir Karim Radi), under the supervision of the Dean of the College of Education for Pure Sciences A .Dr. Hamida Idan Salman esteemed. The aim of the thesis was to prepare the nano-material (dihydroxide layer), and use the Zn/AI-LDH dihydroxide nano-layer for the adsorption of negative ions (carbonates, phosphates) from water, and to study the effect of temperature and the acidity function of negative ion adsorption.
The study concluded, that the adsorption isotherms of carbonate and phosphate ions on the surface of the zinc / aluminum dihydroxide layer are similar to the type S1,S2 according to Giles classification, meaning that the adsorption follows the Freundlich equation, and the adsorption reaction of carbonate and phosphate ions on the zinc / aluminum dihydroxide layer is an emitter reaction to heat.
The researcher recommended the use of dihydroxide layers as negative ion exchangers, catalyst and corrosion inhibitor, and studying the adsorption kinetics of organic materials on the surface of nanocomposites, which is of wide importance in water purification. These nanomaterials can be used in several other fields, such as the field of agriculture, where it works to trap polluting materials between the layers of the soil and then control its release. danger to human health. The student was awarded with distinction.
