제목 Radiation Induced Cross-Linked Carboxymethyl Starch for Removal of Metal Contaminants from Water
초록 This work describes the synthesis of low-cost chelating material derived from starch for adsorption of heavy metal ions from aqueous solution. The first part of the work deals with the chemical modification of corn starch with sodium monochloroacetate to obtain the carboxymethyl starch (CMS). Following carboxymethylation, the CMS was cross-linked using electron beam radiation (EB-radiation), resulting in a cross-linked carboxymethyl starch (CCMS). The modified starch derivative was characterized for degree of substitution (DS) using back titration method. Carboxyl groups introduced in the modified starch was confirmed by FT-IR analysis. Morphological study of the modified starch was carried out using WAXS analysis. In the second part of the work the CCMS was evaluated for the removal of metal contaminants from water.
