Synthesis of a new Chelating Corn Starch and Application on Preconcentration of Copper (II)

摘要：

A chelating starch (SMAEN) containing amidocyanogen and acyl functions was prepared through a two-step reaction.The structure of SMAEN was determined by FTIR spectrum.The amination extent was traced by estimating the nitrogen content of SMAEN.The SMAEN was tested as an adsorbent in Cu2+ metal aqueous solution.The parameters influencing the efficiency of preconcentration Cu2+ including sample acidity,adsorption conditions were investigated.The Cu2+ ion was accomplished good adsorption amount at pH＞4.The maximum adsorption capacity was 2.69mmol per gram of dried SMAEN.
