Abstract
2,4-Dihydroxy-5-bromopropiophenone thiosemicarbazone
(DHBPT) was synthesized and used as a spectrophotometric reagent
for nickel. Ni(II) forms yellow coloured complex between pH range
7.0 to 10.0 and shows maximum absorption at 375 nm. Molar
absorptivity for Ni(II)-DHBPT is 2.586 x 103 L/mole cm. Ni(II) DHBPT
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.
