Abstract:In this study two Polyacrylonitril-Ti(IV) tungstophosphate organo-inorganic ion exchangerswith different molar ratios have been synthesized. These ion exchangers have been characterized byFT-IR, X- ray diffraction, TG, SEM and CHNSO techniques and their cation exchange capacity has been

measured by continuous method. Distribution coefficients (Kd) for metal ions and radionuclides weredetermined by batch method andwith these ion exchangers, separation of metal ions was achieved on aglass column.

Keywords:Ion Exchanger, Polyacrylonitrile-Ti(IV) Tungstophosphate, Metal Ions, Cation ExchangeCapacity, Separation, Batch Method, Distribution Coefficient
