Chemical Studies For Sorption Of Some Radionuclides On SSilico(IV) Titanate As Cation Exchanger

SUMMARY AND CONCLUSIONOne of the most common treatment methods for such aqueous streams is the use of ion exchange, which is a well developed technique that has been employed for many years in both the nuclear industry and in other industries.This thesis is concerned with some fundemental studies related to the separation and preconcentration of some radionucloides, namely, sodium-22, cesium-137, cobalt-60 and europium-152+154. The main aim of this study is direct to prepare silicotitanate samThe work carried out in this thesis is summarized in to three main parts; namely, introduction, experimental and finally results and discussion.The first chapter is introduction and literature which includes a brief account on the classification of synthetic ion exchange, silicotitanate as in organic ion exchanger, Characterization and Physicochemical Properties of Inorganic Ion Exchanger, ApplicA literature survey related to different synthetic inorganic ion exchangers and natural materials for separation of certain radionuclides of importance in nuclear technology was reviewed.The second chapter is materials and methods which includes the chemicals used and their chemical purity, the method of preparation of silicotitanate as well as the instrumentation, the analytical techniques and the procedures used in this thesis.The third chapter deals with the results and discussion and is divided into main sections namely; preparation and characterization of adsorbent materials, distribution studies, kinetic studies and sorption isotherms in the first section from third chapter
