College of Education for Pure Sciences Discusses a Master’s Thesis on the Preparation of Some Interfering Mesh Polymers and the Study of their Properties in Removing Heavy Ions from Water

Discussion of a Master’s Thesis

Department of Chemistry at the College of Education for Pure Sciences discussed the master’s thesis tagged (Preparation of some reticulated polymers and studying their properties in removing heavy ions from water), by the student (Asraa Qahtan Abdel Amir), under the supervision of the Head of the Department of Chemistry (Prof. Dr. Sajid Hassan Kazar).
The study aimed to prepare semi-IPNs through the use of low-cost materials, including drinking water bottle waste (PET), mixing it with epoxy and risol, making use of drinking water bottle waste and converting it into environmentally friendly materials, and diagnosing polymers with FTIR technology. Conducting thermal and weight analyzes using TGA and DSC techniques, studying the loading capacity of polymers and showing the effect of treatment time and acidity function on the analytical efficiency of the polymers prepared with the studied ions, and studying the Freindlich and Lankemeier adsorption isotherms for polymers. The study also concluded the possibility of recycling environmental waste in economical ways with low cost into useful materials, as this study included converting waste drinking water bottles (PET) by glycolysis into two types of overlapping mesh polymers Semi-IPNs-1 and Semi-IPNs-2 and using them in Purification of industrial and domestic wastewater and selection of toxic ions (Co+2, Cd+2, Pb +2, Ni+2) through the use of adsorption technology, based on the pH function).
The discussion came out with many recommendations, including: studying the adsorption process on other ions such as mercury ion, copper and other ions, studying the effect of temperature on the adsorption process, studying the selectivity process to remove ions and the possibility of making polymeric sensors. The student received an honors grade.
