Synthesis and characterization of poly(hydroxamic acid) chelating resin from poly(methyl acrylate)-grafted sago starch

A new chelating ion-exchange resin containing the hydroxamic acid functional group was synthesized from poly(methyl acrylate) (PMA)-grafted sago starch. The PMA grafted copolymer was obtained by a free-radical initiating process in which ceric ammonium nitrate was used as an initiator. Conversion of...
