| Abstract: | In this paper the simultaneous determination of zinc and copper with 5-Br-PADAP at PHS.5 by using derivative spectrophotometry has been studied.The malar derivative absorption coefficients of zinc and copper are 3.0×105 and 1.0×105 respectively.The interference of overlapped spectra was overcome.Satisfactory results were obtained in the determination of zinc and copper in hair. |

| Keywords: | Br-PADAP derivative spectrophotometry zinc copper determination hair. |
