摘要:

A comparative study was carried out to determine 21 pesticides in environmental water samples by high performance liquid chromatography using both liquid-liquid (LLE) and solid-phase (SPE) extractions. The reproducibility of the SPE method is better than employing LLE with dichloromethane. but SPE was more efficient to recover metomyl, dimethoate, chlorpyrifos ethyl and carbophenothion.
