摘要：
A method based on liquid extraction followed by sample enrichment on reversed-phase solid-phase extraction was developed for the extraction of five degradation products of four sulfonylurea herbicides (chlorsulfuron, metsulfuron-methyl, thifensulfuron-methyl and tribenuron-methyl) from soil. The compounds have been quantified by LC-W and identified by tandem LC-MS with electrospray ionization or atmospheric pressure chemical ionization. The limits of detection for the five compounds were between 10 and 50 mu g kg(-1). The method has been applied to the extraction of soil samples after microbial degradation of sulfonylurea herbicides. (C) 1999 Elsevier Science B.V. All rights reserved.
