A new method based on matrix solid phase dispersion-capillary electrophoresis with electrochemiluminescence detection (MSPD-CE-ECL) has been developed for the simultaneous determination of three kinds of phenylurea herbicides (PHUs). Poly-β-cyclodextrin (poly-β-CD) was used as an additive in the running buffer to improve the separation of three analytes. The conditions for CE separation, ECL detection and effect of poly-β-CD were investigated in detail. Under the optimal conditions, three kinds… CONTINUE READING
