Abstract

The present thesis has three main chapters: Chapter I (Introduction): This chapter represents a scientific literature survey with advantage of chelating resins. Different chelating resins with various functionalities and their applications in the extraction and separation of uranium and vanadium ions were also reported. Chapter II (Experimental): It includes a detailed account about methods of preparation, investigation as well as the uptake behavior of investigated resins towards uranium and vanadium ions. Chapter III (Results and Discussion): Part (1): Modified chelating resin was obtained through grafting copolymerization of glycidyl methacrylate onto cellulose. The obtained resin was functionalized by amine groups and named R1. The adsorption behavior was tested towards uranium and vanadium ions. Thermodynamic studies revealed that the adsorption process of U(VI) on resin R1 is an exothermic spontaneous reaction and becomes more favorable at lower temperatures. Prepared resin was regenerated for repeated use by diluted H2SO4. The studies also revealed that R1 is highly efficient for extraction and separation of U(VI) ions from their synthetic solutions as well as real samples. Part (2): Modified chelating resin was obtained through grafting copolymerization of glycidyl methacrylate onto cellulose. The obtained resin was functionalized by iminoacetate groups and named R2. The adsorption behavior was tested towards uranium and vanadium ions. Thermodynamic studies revealed that the adsorption process of V(IV) on R2 is an exothermic spontaneous reaction and becomes more favorable at lower temperatures. Prepared resin was regenerated for the repeated use by diluted H2SO4. The studies also revealed that R2 may be used for efficient and selective extraction of V(IV) ions over U(VI) ions from their synthetic solution mixture as well as real samples.
