摘要
建立高效液相色谱法,采用紫外检测器和CHIRALCE OD-H柱,以正己烷、乙醇(95∶5,V/V)为流动相,在238 nm波长下进行25%噁唑·氰氟乳油中有效成分的含量测定。结果表明,噁唑酰草胺和氰氟草酯的线性相关系数分别为0.999 1和0.999 3,变异系数分别为1.03%和0.58%,平均回收率分别为99.82%、99.54%。此方法的精密度及准确度良好,均符合分析标准,可用于复配产品中的唑酰草胺和氰氟草酯的检测分析。
A quantitative analysis method was introduced for the determination of metamifop cyhalofop-butyl 25%EC by HPLC on CHIRALCE OD-H column with ultraviolet detector at 238 nm.The mobile phase was made up of n-hexane and ethanol(95:5,V/V).The results showed that the linear correlation coefficients of metamifop and cyhalofop-butyl were 0.9991 and 0.9993,the coefficients of variation were 1.03%and 0.58%,and the average recoveries were 99.82%and 99.54%,respectively.The precision and accuracy of the method were good.It could be used for the determination of metamifop and cyhalofop-butyl in compound products effectively.
