| Abstract: | A decatalytic spectrophotometric method based on a copper catalyzed redox reaction between K\-2S\-2O\-8 and methyl red has been developed for the determination of trace quantities of copper in the presence of H\-3PO\-4. The detection Limit for copper is 8 349×10 -12 g/mL and the linear range of determination is (0 01～0 08)μg/25mL. Satisfactory results were obtained for the determination of trace copper in human hair, food samples and water samples. |
