%X Composite sorbents based on hydrous oxides of cerium and zirconium were used for selective removal of Sb(V) oxoanion. The effects of pH, concentration of Sb and accompanying anions in the feed solution and kinetic of the sorption were studied. Both CeO2.nH2O/XAD-7 and ZrO-PAN sorbents showed maximum sorption of Sb(V) oxoanions at pH of 3.5. Sorbent CeO2.nH2O/XAD-7 showed higher removal efficiency than ZrO-PAN. In both cases, increased concentration of sulfates and chlorides in the feed solution caused a decrease of Sb(V) removal
