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

Abstract:

Article Preview

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.
