Abstract
To improve pre-treatment methods in vegetables organophosphorus pesticide residue detection, GB method, oscillation extraction method and ultrasonic extraction have been used to extract the pesticide residue in vegetables; And then enzyme inhibition method was used to determine the effect of ultrasonic time and the affects of three different ways (direct measurement, active carbon adsorption after filtration and 0.45 μm film filtration) were compared. The best pre-treatment methods was ultrasonic extracting for 10 min followed by a 0.45 μm film filtration, with which the response rate was the highest. Compared with the GB method, the accuracy, recovery and reproducibility of this method were higher.关键词
