Abstract

<p>The polarographic and voltammetric behaviour was examined for the title compound, which is the basic component in many commercial optical whitening agents. Dimethylformamide containing 5 vol.% water was chosen as the solvent and tetraethylammonium bromide as the supporting electrolyte. The optimum conditions were found for determining the substance by tast polarography, differential pulse polarography, linear sweep voltammetry on a hanging mercury drop electrode, and differential pulse voltammetry on a hanging mercury drop electrode. The analyte concentration regions for the four techniques were 0.1 - 0.5, 0.01 - 0.5, 0.01 - 0.5 and 0.01 - 0.1 mmol l<sup>-1</sup>, respectively. Practical applicability of the methods to the determination of the title compound in technical products was verified.
