Abstract

The optimum parameters to extract the eighteen residual pesticides from the aqueous sample were established and the extracts were analyzed by GC-μECD with good sensitivity. To establish the optimum extraction conditions, species of extraction solvent, pH of sample, salt-out effect, ratio of sample to extraction solvent, movement speed of plunger were investigated. As a result, limit of quantification was 0.5 ng/mL, relative standard deviations were between 6.0% and 51.4% and the linearity of calibration curves was good.
