Fal'kovskaya, N. Sverdlova, Yu. Dedkov] The direct potentiometric determination of copper(II) using chalcogenide glass electrodes was studied in solutions containing azo dyes. The association of azo dyes, most pronounced in aqueous solutions of acid Blue 2K, was demonstrated by spectrophotometry. The interfering effect of reagent association on the results of the potentiometric determination of copper(II) was found. Pleiades Publishing, Ltd., 2007 Fal'kovskaya A.
