L. Ramesh Babu & K.Kiran*

Journal Title:Journal of Chemical, Biological and physical sciences

The author successfully synthesized 4-dimethyl amino benzyl thiourea and it gives a yellow colored complex with copper metal solution in sodium acetate-acetic acid buffer of pH 5.5. Maximum absorption is found at 390 nm. Various factors such as pH, reagent concentration and choice of the solvent, foreign ions effects were studied. This method is successfully applied for the determination of copper in various environmental samples.
