Study on the optimization method for determination of lamnbda-cyhalothrin CS by HPLC
Based on existing methods,the destruction effect on microcapsule capsule wall using different solvents were investigated,and a separation and quantitative analysis method for lambda-cyhalothrin CS was established by HPLC,with ethanol as solvent,n-hexane and ethanol as mobile phase,on ZORBAX RX-SIL column and DAD at 278 nm wavelength.The results showed that the linear correlation coefficient was 0.999 9 at the concentration of 0.05-1.0 mg/mL,the standard deviation was 0.06,the relative standard deviation was 0.55％,and the average recovery was 100.81％.The method had the advantages of rapidity,simple operation,accuracy and good separation effect.
