Abstract
Micellar electrokinetic chromatography (MEKC) using sodium dodecyl sul fate was tested for its ability to analyze mixtures containing three d ioxin derivatives. Dioxin-containing samples, subjected to photocataly tic oxidation using TiO2 and/or SnO2 as the semiconductor catalyst wer e analyzed by MEKC to obtain the rate constant for each dioxin when it was degraded individually or in the presence of the other two dioxins . A significant degree of analyte competition was observed and the mix ed catalyst offered important synergism. (C) 1998 Elsevier Science Ltd . All rights reserved.
