ABSTRACT
Objective To develop a suitable solid-phase extraction(SPE)method for the further purification of the test solu- tion in suppositories of Chinese medicinal materials which are made of lipid soluble bases,and to detect the residues of 20 kinds of organochlorine pesticides(OCPs).Methods Different kinds of SPE columns were selected and several elution solvents were used for the purification of the sample of herbal medicine of Huazhi Shuan,and then the residue contents of OCPs were determined by GC-ECD method.Twenty kinds of OCPs were added into the samples and the efficacy of the methods were eval- uated by the obtained recoveries.Results The recoveries of the 20 kinds of OCPs being detected were basically comply with the requirements for the analysis of pestiside residues.Conclusion After the tested solution is obtained from GPC column and is further purified through florisil SPE column,the impurity can be removed and the high accuracy of the quantitative analysis of the compounds can be achieved.
