Анотация: A new chelating polymeric sorbent has been synthesized on the basis of styrene maleic anhydride copolymer by the chemically modification with hydrazide of maloney acid. The synthesized sorbent and its complex with metal has been investigated by IR spectroscopy and its sorption characteristics toward vanadium (V) ions have been studied. Synthesized sorbent has been applied for investigation of pre-concentration of V (V) ions in liquid phase. The optimal sorption conditions such as effect of pH, ionic strength, effect of initial metal ion concentration and time to reaching chemical equilibrium on sorption have been established. The synthesized sorbent was selective to vanadium ions within better response time of 120 min. In static state adsorption was found to be pH dependent with maximum removal efficiency at 4. The removal efficiency of vanadium (V) increased by increasing of initial vanadium (V) concentration. The maximum adsorption capacity of vanadium (V) onto this adsorbent has been established and found to be 183.6 mg·g-1. The proposed method has been successfully applied to the determination of micro amount of vanadium in industrial water samples. Also desorption of vanadium ions with mineral acids of the different concentrations has been studied. Results of desorption have been represented in this work.
