The quantitative analysis method of pendimethalin EC in emulsifiable concentrate was developed by High Performance Liquid Chromatography ( HPLC ) consisting ultraviolet absorbance detector , the analytical column was a SunFireTM C18 column . The mobile phase was an acetonitrile-water ( 80:20 , v/v ) at a flow rate of 1 mL/min . The temperature was kept at 30 ℃. The wavelength of detector was set at 240 nm . The results showed that the linear correlation coefficient of the analytical method for pendimethalin was 0.999 9,the standard deviation was 0.045,the coefficient of variation was 0.14%,and the average recovery ratio was 99.47%. The method is simple,rapid,accurate and reproducible and can be used for quality control of pendimethalin in emulsifiable concentrate.
