The material was found to be granular and can be conveniently used in column operations. The material was characterized by various analytical techniques. The material showed higher ion exchange capacity (1.48 meq/g) than its inorganic counterpart (1.1meq/g). Effects of temperature and ionic radii on ion exchange capacity, chemical stability in various solvents, pH titration studies were also carried to understand the ion exchange capabilities. The distribution co-efficient studies of metal ions in various electrolytes on exchanger revealed that the material is highly selective for Bi3+ and Th4+, which are toxic environmental pollutants. The selectivity of various metal ion was found to be in the order Bi3+ & Copyright@ International Science Community Association
