The results showed that the linear correlation coefficients of topramezone, nicosulfuron and atrazine were 0.999 6, 0.999 2 and 0.999 5, the standard deviations were 0.055, 0.063 and 0.210, the variation coefficients were 2.59%, 2.99% and 1.03%, the average recoveries were 98.41%, 99.54% and 99.23%, respectively. The method was simple, rapid, accurate, and suitable for the qualitative and quantitative analysis.
