摘要
建立了固相微萃取（ＳＰＭＥ）与气相色谱（ＧＣ）联用测定蔬菜中残留有机磷农药的方法．该法包 括蔬菜样品的预处理、ＳＰＭＥ 萃取及气相色谱测定，其灵敏度高、重现性好，且简单易行．方法检测限 分别为甲拌磷０．２５ｎｇ／ｇ；二嗪农０．３０ｎｇ／ｇ；甲基对硫磷０．５５ｎｇ／ｇ；乙硫磷０．４０ｎｇ／ｇ．文中还就 影响ＳＰＭＥ 萃取的诸因素及该法的可行性等作了探讨．
A method of solid phase microextration (SPME) coupled to gas chromatography (GC) for the determination of organophosphorus pesticide residues in a food plant, including the sample preparation, SPME extraction and GC determination,was developed. Good sensitivity and reproducibility were achieved with very simple, facile procedures. Estimated detection limits of the method for the determination of phorate, diazinon, methyl parathion and ethion in food plant Chrysanthemun coronarium were 0. 25, 0. 30,0. 55, 0. 40 ng/g, respectively. Some factors influencing SPME extraction and feasibility of the method were also discussed.
