Removal of toxic metal ions from metal-finishing wastewater by solvent extraction
Journal Article

· Sep. Sci.; (United States)
Solvent extraction procedures are presented for the removal of chromium, cadmium, and zinc from metal-finishing wastewater. The procedures utilize a 25% Alamine 336-xylene solution as the extractant. The three metals can be extracted selectively or simultaneously using a 100 to 1 aqueous phase to organic phase ratio. All three metals can be stripped from the organic phase with better than 99.5% efficiency with 4 M NaOh. The regenerated reagent can be recycled and reused without any loss of extraction efficiency. The procedures are reproducible, rapid, and simple.
