A method for determining the complex formulations by HPLC was established under the same conditions atrazine·acetochlor·2,4-D butylate 60% SE emulsion droplets atrazine, acetochlor, and 2,4-D butylate content, using C18 column stainless steel column with acetonitrile-water as the mobile phase, the detection wavelength of 235 nm, the sample of atrazine, acetochlor, and 2,4-D butylate quantitatively. Experiments showed that the use of this method for determining the standard deviation of the preparation of atrazine, acetochlor and 2,4-D butylate content were 0.12, 0.16 and 0.11 , the measurement results of coefficients of variation were 0.58%, 0.52% and 1.08%, and experimental average recovery of the method were 99.21%, 99.60% and 98.94%.
