摘  要:
[目的]建立在同一液相色谱条件下测定混配制剂中2甲4氯钠、莠灭净和敌草隆含量的分析方法。[方法]采用C18柱,用乙腈-水(0.1 mol/L KH2PO4,体积比40∶60)为流动相,检测波长为210 nm,外标法定量。[结果]2甲4氯钠、莠灭净和敌草隆的线性相关系数分别为0.9997、0.9995、0.9998;标准偏差分别为0.19、0.25、0.22;变异系数分别为1.81%、0.60%、0.94%;平均回收率分别为100.0%、100.1%、99.9%。[结论]在同柱同操作条件下分析73%甲.灭.敌草隆WP,简便、快速、稳定可靠,是一种较理想的分析方法。

摘  要:
[Aims] The research aimed to establish a HPLC method for the determination of MCPA-sodium,ametryn and diuron in 73% WP.[Methods] The HPLC conditions were C18 column,acetonitrile-water(0.1 mol/L KH2PO4,40∶60,by vol) as mobile phase,UV detection at 210 nm,and an external standard method.[Results] The linear correlations of MCPAsodium,arnetryn and diuron were 0.9997,0.9995 and 0.9998 respectively.The standard deviations were 0.19,0.25 and 0.22 respectively.The variation coefficients were 1.81,0.60 and 0.94% respectively.The average recoveries were 100.0,100.1 and 99.9% respectively.[Conclusions] The analytical method for determination of MCPA-sodium,ametryn and diuron in 73% WP at one column and one condition is simple,rapid and reliable.It′s a preferred method of analysis.
