摘　　要：本文介绍以ODS色谱柱,UV240nm为检测波长,用乙腈/水=48/52(V/V)(用磷酸调至pH4.0-5.0)做流动相,在ODS色谱柱上同柱液相色谱法测定烟嘧磺隆和莠去津含量,其变异系数分别为0.86%和1.17%,回收率分别在99.46%-100.54%和98.57%-100.27%范围内,相关系数分别为0.9897和0.9903。Nicosulfuron + atrazine in mixture were determined by high performance liquid chromatography simultaneously using ODS column , UV240nm detection, a mobile phase of acetonitrile +water =48 +52 ( V/V) -in this paper.The variation coefficients of nicosulfuron and atrazine were 0.86% and 1.17% .recoveries were 99.46%-100.45% and 98.57%-100.27%,linear correlations were 0.989 7 and 0.990 3 respectively.
