Synthesis of Polymeric Chelating Ligands from Sago Starch for Metal Removal from Electroplating Wastewater
Polymeric chelating ligands containing hydroxamic acid and amidoxime ligands were synthesized from poly(methyl acrylate-co-acrylonitrile) grafted sago starch. Batch adsorption was performed to identify the binding property of metal ions. Maximum sorption capacity of copper is 2.80 mmol g-1, however,...

Summary: | Polymeric chelating ligands containing hydroxamic acid and amidoxime ligands were synthesized from poly(methyl acrylate-co-acrylonitrile) grafted sago starch. Batch adsorption was performed to identify the binding property of metal ions. Maximum sorption capacity of copper is 2.80 mmol g-1, however, other transition metals has good sorption capacity with this legends. The rate of exchange of some metals was fast, i.e. t½ 6 minutes (average). Three types of wastewater containing chromium, zinc, nickel, copper, and iron were used in this study. The metal recovery is found to be high, and more than 99% of the metals could be removed from the metal plating wastewater. Polymeric chelating ligands could be used to remove the metals from wastewater. |
