Abstract

A resin containing the hydroxamic acid functional group was synthesized from poly(methyl acrylate)-PMA grafted sago starch. The conversion of ester groups of the grafted copolymer into hydroxamic acid was carried out by treatment of the polyester with hydroxylamine in an alkaline solution. The characterization of the poly(hydroxamic acid) chelating resin was performed by FTIR analysis. The hydroxamic acid functional group was identified by infrared spectroscopy. The sorption of the prepared resin toward some metal ions was investigated by a batch technique. The binding capacity of copper was maximum at pH 6 and the capacity was 2.244 mmol/g. The rate of exchange of the copper ion was, t⅟₂ = 7 minutes. It was also observed that the metal ion sorption capacities of the resin were pH dependent and its selectivity toward the metal ions is in the following order: Cu²+ > Pb²+ > Cd²+.
