Abstract
A method was developed for the determination of abamectin in pesticide products by HPLC with VWD detectors.Samples dissolved by acetonitrile were determined by rp-HPLC with the chromatographic column of C18,the mobile phase： methanol-water（85∶15）,the flow rate was 1.0 mL/min,the amount of injection was 10 μL,and the temperature of the detector was 40 ℃.The preserving time,peak value,peak areas of the active ingredients in the standard sample of abamectin were determined.Results were the preserving time of B1a was 13.3 min while that of B1b was 10.3 min.The concentration of abamectin was positively related to the peak area with linear equation of y =0.040 7 x-0.181 9（r = 0.999 9）,the reclaiming rate was between 96.0% and 102.0%,the precision and coefficient of variability was between 0.36% and 0.58%.The results showed that the determination method was accurate and sensitive,it could be used for the routine analysis of abamectin＇s content in pesticide products.关键词
