| Abstract: | Complex formation equilibria between Ni(II) with benzyldithiocarbamate, phenyldithiocarbamate and dibutyldithiocarbamate have been studied spectrophotometrically at (25±0.1)°C in 0.1M diethanolamine/diethanolamonium ionic strength and pH 8.8 that prevents ligand decomposition, frequent in acid medium. The stability constants and molar absorptivity coefficients have been evaluated for the three complex species obtained in each case. |
