Abstract
A method for the spectrophotometric determination of cobalt, based on the formation of a coloured chelate (λmax. 480 nm, εmax. 2.83 × 104 l mol–1 cm–1 and colour contrast 134 nm) with benzyl 2-pyridyl ketone 2-pyridylhydrazone, is described. Under the optimum conditions, colour development is instantaneous and the colour is stable for several weeks. Under appropriate working conditions, the method is applicable to the determination of cobalt in manufactured paints and environmental samples of paint. The fundamental solution chemistry of the reagent and a brief description of its more interesting colour reactions are also reported.Keywords
