Chromium and cadmium are toxic heavy metals present in wastewater from electroplating industries. The removal of Cd (II) and Cr (III) by Amberjet, IR 1200, a synthetic ion exchange resin has been studied. The resin was prepared into two cationic forms H+ and Na+ . The optimum conditions were concentration, pH, stirring time and resin amount. The exchange capacities, moisture content and optimum conditions of this resin were determined in a batch system. The stirring speed was 50 ppm during all the batch experiments. The initial and final chromium and cadmium amounts were determined using the atomic adsorption spectroscopy. The most preferable value of concentration is 10 mg/L; pH is 5.5, stirring time 30 min, amount of resin 200mg. The maximum removal and recovery for Cd (II) and Cr (III) was seen in Na + form of resin.
Keywords: Cadmium, Chromium, heavy metal, water contamination, resin, ion-exchange, extraction, effluent.
