| Abstract: | Synthesis and characterization of a new chromogenic reagent, l-(p-azophenyl)-3-(2-thiazol)triazene(APTT), are described. The reagent has been used for spectrophotometric determination of zinc(II) APTT forms a red colored complex with zinc(II) in alkaline m dium in the presence of Triton X-l00. The optimum conditions for the colour reaction have been descried. The molar absorptivity of the complex is 9.6 X 104 1.moI-1 cm-1 at 545 nm. Beer's law is obeyed over the range 0 - 2 µg/25ml Zn(lI). lnterference due to several ions has been studied. The recommended method has been applied to the determination of zinc(II) in aluminum alloys. |
