Abstract:
Objective A method for quantitative determination of 16 kinds of organochlorine pesticide (OCPs) in aquatic prod-ucts by gas chromatography (GC)was established .Methods The sample was extracted by acetonitrile ,purified by Carb/NH2 ,and then determined by GC .Results The linear relations of 16 kinds of OCPs were good at 0 .05 - 1 .00 mg/L(r> 0 .998) .The limit of detection of OCPs was in the range of 0 .04 - 0 .31 μg /kg(S/N = 3) .When the standard levels were 50 ,100 ,200 μg /kg ,the recovery rates were 72 .6% - 115 .2% ,the relative standard deviations were 0 .6% - 7 .5% .Conclusion The method established in this stud-y is applied to the determination of 16 kinds of OCPs in real samples with satisfactory results .
