摘要
采用Dianmonsil-C18反相色谱柱和紫外检测器以甲醇和pH值3.0的磷酸水溶液为流动相(体积比70∶30),检测波长240nm,对试样中嘧草硫醚含量进行液相色谱分离、测定。嘧草硫醚的保留时间为7.432min,变异系数为0.65%,回收率为99.67%～100.31%,线形相关系数为0.9962。
A HPLC method of Pyrithiobac-sodium for quantitative determination. It was established by using Dianmonsil- C18 column, methand warter（70：30, by vol）as the mobile phase, and UV detector at 240 nm. The water used before must be pH=3 which was mixed weth phosphoric acid. The result showed that the retention time was 7.432 min, RSD was 0.65%, recovery was 99.67-100.31%, and liner correlation coefficitnt was 0.9962.
