Studies of the Color System of Zn(Ⅱ)-TPPS4-CTAB and the Determination of Trace Zinc with Triwave-length Spectrophotometry

Abstract

Abstract: Zinc(Ⅱ) reacts quickly with tetrakis- (4-sulphophenyl) porphyrin (TPPS₄) and cethyltrimethylammonium bromide (CTAB) in the presence of mercury(Ⅱ) at room temperature. The complexes Zn(n)-TPPS₄-CTAB, Hg(Ⅱ)-TPPS₄-GTAB and the reagent show maximum absorption wavelengths at 427 nm, 447 nm and 417 nm, respectively. Anew method for the determination of trace zinc with triwavelength spectrophotometry is described and the molar absorptivity is 8.5 ×10⁵L·mol^-1cm^-1. After the ion-exchange separation, this method is of high selectivity and has been successfully applied to the determination of zinc in aluminium alloys, ores, natural water and human hair.

Key words: Zinc, Tetrakis-(4-sulphophenyl) porphyrin, Triwavelength, Spectro- photometry
