The internal standard was dimethyl phthalate , the chromatographic column was TR-5 capillary column. The results showed that the linear correlation coefficients of nicosulfuron and atrazine were 0.999 1 and 0.999 6, the standard deviations were 0.043 and 0.143, the variation coefficients were 1.44% and 0.71%, the average recoveries were 98.10%-102.09% and 98.59% -102.12%. The method was a suitable analytical method with fast speed, high precision and accuracy.
