| Abstract: | The method is based on the colour reaction of Cd and Co with 5-Br-PADAP in the weakalkaline medium. The first derivative spectrophotometric method can reslove the overlapping ofabsorption spectra for Cd and Co. This method proves satisfactory for the simultaneous deter-mination of micro amounts of Cd and Co in synthetic samples. |
