title: The complexation of Cr(III) and Cr(VI) with flavones in micellar media and its use for the spectrophotometric determination of chromium.
abstract: The complexation of chromium by different flavonoid dyes in micellar media has been studied, in particular the reaction between chromium and quercetin. Micellar effects, the reaction pathway proposed and the application of the method to the determination of Cr(VI) and Cr(VI) + Cr(III) mixtures are discussed.
