Abstract

1,6-Dimercapto-1,6 -diamino-2,4,5-triaza-3-phenyl-3-hexene (MAAPHE) was synthesised and used as a spectrophotometric reagent for nickel. Ni (II) forms pale yellow coloured complex between pH range 7.0 to 11.0 and shows maxm absorption at 385 nm. Molar absorptivity for Ni- MAAPHE is 2.850 x 103 L/mol/cm. Ni-MAAPHE has 1 : 2 (M : L) stoichiometry. Beer’s law is obeyed up to 16.49 ppm for Ni (II). The reagent has been found to give satisfactory results for the analysis of nickel in German-silver alloy. Formation of the complex has been supported from the IR spectral data.
