Studies on sorption characteristics of a novel inorganic ion exchanger for treatment of radioactive waste solutions

The nuclear industry produces large volumes of radioactive waste solution, which requires treatment prior to final disposal or storage. Various types of inorganic and organic ion exchangers have been used for this purpose; however inorganic ion exchangers generally are superior to organic resins because of their greater resistance to high temperature and high radiation which is of great importance in the nuclear technology. This dissertation presents a development work of new highly efficient heteropolyacid-based inorganic ion exchanger; Zirconium molybdo tungsto vanado silicate aimed for the treatment of nuclear waste solutions. The focus has mainly been on the removal of several key radionuclides (137Cs, 124Sb and 154Eu) from liquid radioactive waste and 147Nd,153Sm and 140La from aqueous under simulated conditions using batch technique
