VINYL RESINS WITH RETENTION PROPERTIES FOR HEAVY-METAL IONS

Resins with carboxylic pendant groups were synthesized. The resins wer e characterized by elemental analyses and FT-IR spectroscopy, and the ability to bind copper(II) and uranium(VI) by batch method at differen t pH was studied. Uranium(VI) is adsorbed at pH 3 and pH 4 above 88%. The maximum capacity of load for uranium(VI) is higher than IRA-400, a commercial resin. Elution assays for Cu(II) and U(VI) from the loaded resins with sulfuric acid and sodium carbonate were also carried out.
