Abstract

<p>The polarographic behaviour of the title optical whitening agent was studied in aqueous-methanolic solutions. Conditions for its quantitation were found within the concentration regions of 10 to 100 μmol l<sup>-1</sup> by tast polarography, 1 to 100 μmol l<sup>-1</sup> by differential pulse polarography on the conventional dropping mercury electrode, and 0.1 to 10 μmol l<sup>-1</sup> by differential pulse polarography on a static mercury drop electrode. The analytical procedures developed were applied to the determination of the compound in technical products.
