| Abstract: | [Objective] To determine the pesticide residues in soil by GC.[Methods] After the pesticide residues were extracted from soil with acetone-water(7∶3,V/V),were Liquid/liquid extracted by normal hexane.Extracts were clean-up by alumina neutral-florisil column.Analytical screening was determined by gas chromatography using capillary column equipped with electron-capture detector.[Result] The correlation coefficients were 0.990 3-0.999 1,the precisions of instrument were 1.2%-3.4%.The precisions of methods were from 6.5% to 7.4%.The recoveries were from 84.0% to 103.2%,RSD was 2.5%-8.8%.[Conclusions] A satisfactory result was obtained in the determination of the pesticide residues in soil. |
