Abstract

The reagent was synthesized and characterization was carried out by FTIR, NMR, elemental analysis as well as Mass spectrometry. The synthesized reagent was then applied for the development of the analytical method for the  extractive  spectrophotometric determination of  cobalt  (II).  Cobalt  metal  forms  pale  yellow  coloured complex, which can be extracted in chloroform at pH 9.4 having absorption maxima at 415 nm. Beer’s law is obeyed in the concentration range 1-8.00 μg. The molar absorptivity and Sandell’s Sensitivity of the extracted species are 7.1724 X 103 Lit mol-1 cm-2 and 8.2165 X 10-3μg cm-2 respectively. The developed method is highly sensitive, selective, simple, rapid, accurate, and has been satisfactorily applied for the determination of cobalt in the synthetic mixtures, pharmaceutical samples, and alloys.
