Functional polyethyleneimine chelating resin(PEIDT) was obtained from the amine group on the molecular chain of polyethyleneimine with a carbon disulfide (CS2) under alkaline condition of sodium hydroxide.PEIDT was evaluated by FT-IR and studied the effects of PEIDT on the adsorption performance for Co2+ in cobalt sulfate water samples under different pH values and Co2+ ion's initial concentration.The results showed that xanthate was successfully introduced to polyethyleneimine molecular chain to form the functionalization,the resin can adsorbing and remove Co2+ ions in the water solution of cobalt sulfate.When pH=6.0,the initial concentration of Co2+ ions was 25mg/L,the removal rate of Co2+ ion could reach more than 90% with the addition of PEIDT was 300mg/L.
