Abstract:
Objective An analytic method with rephase high pressure liquid chromatogrophy(RP-HPLC) was developed to determine the residue of deltamethrin in water.Methods Water sample was filtrated and determined by RP-HPLC.Chromatographic column was YMC C_(18)(250 mm?4.6 mm,5?m),mobile phase was methanol:water=90:10(V/V),the flowing rate was 0.8 ml/min, DAD detecting wavelength was 205 nm.Results The regression equation was y=655.6 x-1.8,r=0.999 99.The lowest detectable concentration was 2.9?g/L.The recovery rate was 98.0%-102.0%and the relative standard deviation was 0.29%-0.48%. Conclusion The method is proved to be satisfactory in precision,accuracy and sensitivity and can be used for the rapid determination of deltamethrin residue in water.
