40％磺草·莠去津悬浮剂的高效液相色谱分析

摘要

采用高效液相色谱法，使用 Diamonsil －C18色谱柱和紫外检测器，在254 nm 波长下对磺草酮、莠去津进行分离和定量分析。结果表明，该方法磺草酮、莠去津的线性相关系数分别为 R2＝0．9989、R2＝0．996；磺草酮、莠去津的标准偏差分别为0.06、0.15；磺草酮、莠去津的变异系数分别为0.54、0.49；磺草酮、莠去津的平均回收率分别为100.1％、100.0％。%The separation and quantitative analysis of Sulcotrione and atrazine were done with the high performance liquid chromatography using Diamonsil - C18 column and UV detector at 254nm wavelength. The results show that the analytical method the linear correlation coefficient of atrazine were R2 =0.9989 and R2 =0.996 for sulcotrione and atrazine respectively;the standard deviation of were 0.06 and 0.15 for sulcotrione and atrazine respectively;the coefficients of variation were 0.54 and 0.49 for sulcotrione and at-razine respectively;the average recovery were 100.1% and 100.0% for sulcotrione and atrazine respective-ly.
