ABSTRACT
Objective To establish a simple and rapid method for the extraction and detection of residual acetochlor and atrazine in environment. Methods Acetochlor and atrazine in environment were extracted and enriched efficiently by using automatic solid phase extraction system. The sample concentrations were determined by gas chromatography-mass spectroscopy with electron impact ionization and multipolar mass spectra Msn. Results The recovery rates and RSDs of the method were 79.2%-95.1% and 1.73%-8.31% respectively. The detection limit of acetochlor in water and soil were 0.1 ?g/L and 0.005 mg/kg respectively. The detection limit of atrazine in water and soil were 0.05 ?g/L and 0.002 5 mg/kg respectively. Linear range was 0-5 ?g/ml. Conclusion The SPE-GC-MS method can be used to determine acetochlor and atrazine in environment.
