Abstract

A simple and an accurate method has been developed for the estimation of cadmium spectroscopically in water and soil systems. The method involves chelate bond formation of Dimethylglyoxime ligand with Cadmium under feasible and basic medium environment. The method shows 1:2 formation bond in between Cadmium and Dimethylglyoximine. The optimal condition for the formation of bonding between Cadmium and DMG and consequent determination of cadmium was established. The applicability of Beer-lambert law was found in between 0.03 to 0.900 μg/ml. The molar extinction coefficient of Cd (DMG) complex was found to be 1.5 × 10⁵mol^-1 cm^-1. Finally, the method was compared with the already available methods and comparative results shows that the study carried out in the said research seems better and economically feasible.
