This report describes a study on the removal of chromium, cadmium, copper, nickel and zinc from metal finishing wastewater using the high molecular weight amine Alamine 336. The study consisted of an initial phase in which the extraction of the metal ions of interest was studied using synthetic solutions. The second phase of the study involved extraction from actual metal finishing wastewater samples. The results of the study indicated that chromium, cadmium and zinc ions can be extracted simultaneously or selectively using a 100-to-1 wastewater to Alamine-336-xylene solution. The simultaneous extraction procedure appears to have some promise for adoption at the industrial scale. Copper and nickel could not be satisfactorily extracted using this procedure. Chromium, cadmium, and zinc can be stripped from the organic phase with better than 99.5 percent efficiency using 4M NaOH. The regenerated reagent can be recycled and reused without any loss of extraction efficiency. The procedures are reproducible, rapid and relatively simple.
