Abstract

Iminodibenzyl (IDB) and 3-chloroiminodibenzyl (Cl-IDB) are proposed as a new class of spectrophotometric reagents for the determination of micro amounts of mercury(II), nickel(II), copper(II) and cobalt(II) in the presence of 3-methyl-2-benzothiazoline hydrazone hydrochloride hydrate (MBTH) or 4-aminoantipyrine (AAP) as electrophilic coupling reagents. The reaction is carried out in neutral aqueous medium. The blue colour formed shows maximum absorbance at 660 nm using MBTH and 630 nm with AAP. The methods obey Beer's law. The molar absorptivity and Sandell's sensitivity show different values with different metals and reagents. The blue colour can also be extracted quantitatively which can be exploited as an efficient extractive spectrophotometric technique for the separation of metal ion from other interfering species. As many as 15 cations and 12 anions and/or complexing agents listed do not interfere. Both the methods have good reproducibility and can be satisfactorily applied in the determination of metals in industrial effluents and soil samples.
