Abstract
The complex equilibria of gallium, indium and thallium(III) with analytically important 2-(2-pyridylazo)-1-naphthol-4-sulphonate were studied spectrophotometrically using graphical analysis of the absorbance curves and minimization procedures for the absorbance data using the SPEKTFOT program on the Tesla 200 computer. The study yielded a complete picture of the reaction mechanism of these elements with heterocyclic azodyes. Optimum conditions for the spectrophotometric determination of gallium, indium and thallium using this reagent were found.
