Abstract.A simple and direct spectrophotometric method has been developed for the determination of cobalt(II) using N,N-Bis(2-aminobenzoyl)ethylenediamine (Baben). The method is based on the colour reaction between Baben and cobalt(II) in borax buffer (pH 9.2). The studies are carried out at 470nm at which the calculated value of molar absorptivity is found to be 1.102104Lmol1cm1. The system obeys...
