Abstract

A new spectrophotometric method is developed for the determination of Ni (II) in an aquous solution. The metal ion forms a blue colored complex with pyridine 2,3 dicarboxylic acid in acidic medium i.e. at pH 4.0 to 5.5. The complex shows maximum absorbance at 620 nm. Job’s method for continuous variation and mole ratio method shows metal ligand ratio in the complex to be 1:2. The complex is stable for days. The blue colored complex obeys the Beer’s law in the concentration range of 200 to 500 gs  of nickel. The molar absorptivity (  ) is found to be 1.10 x 102 lmole-1cm-1. The method has been used for the determination of Ni+2 in synthetic samples.The complex has been synthesized and FTIR studies has been carried out.
