摘要：

A method for the determination of micro-herbicides (metsufuron-methyl, simazine, atrazine, simetryn, dimethachior, dipropetryn, propanil) in water has been developed by solid phase extraction-high performance liquid chromatography-mass spectrometry. No special sample pretreatment was applied. It is only need to 45 min to analysis a sample. The detection limit obtained was lower than 0.1 mug/L. This method saves much time in sample preparation than that consumed by liquid-liquid extraction (60 fold) and off-line SPE (20 fold), and is more effective than the other methods. By using this method atrazine (1.9 mug/L) and dimethachlor (1.64 mug/L) have been detected in surface water.
