| Abstract: | In this Paper, the derivative spectral behaviour of the reaction of cobalt, cadmium and lead with-meso tetra (4 trimethylammonium phenyl) porphine (T(4-TAP)P) has been studied in the presence of cetylpyridinium bromide (CPB). The third order derivative spectrophotometric method with high sensitivities has been developed for the simultaneous determination of the three component mixture. |
