| Abstract: | The simultaneous determination of cobalt and nickel is based on colour reaction of Co(Ⅱ)and Ni(Ⅱ) with 5-Br-PADAP in the weak alkaline medium. The first order derivative spectroghotometric method can resolve the overlapping of absorption spectra for Co(Ⅱ)and Ni(Ⅱ).This developed method proved to be satisfactory for the simultaneous determination of traces of Co and Ni in synthetic samples. Satisfactory results are obtained in the determination of trace cobalt and nickel in some chemical reagents. |
