摘要
目的:建立高效液相色谱法同时测定克百威、福美双和萎锈灵的含量。方法:试样用甲醇溶解,采用等度洗脱的方法,以甲醇-乙腈-水为流动相,同时对萎锈灵、克百威和福美双进行分离,外标法定量。结果:测定克百威的方法线性相关系数为0.9997,变异系数为1.34%,平均回收率为100.7%;测定福美双的方法线性相关系数为0.9998,变异系数为1.50%,平均回收率为99.4%;测定萎锈灵的方法线性相关系数为0.9998,变异系数为1.42%,平均回收率为101.2%。结论:方法满足农药产品含量分析的要求,可同时测定克百威、福美双和萎锈灵的含量。
Aims： A HPLC method was established for determination of active ingredient in Carbofuran·Thiram· Carboxin 25%FS simultaneously. Methods： The sample was dissolved with methanol and analyzed by RP-HPLC using the mixture ofmethanol and acetonitrile and water as the mobile phase in isocratic elution method. In addition,the quantificaation wascalculated by external standard method. Results： The Linear correlation coefficient for carbofuran was 0.9997,the variationcoefficent was 1.34%,and the average recovery was 100.7%. The linear correlation coefficient for thiram was 0.9998,thevariation coefficent was 1.50%,and the average recovery was 99.4%. The linear correlation coefficient for carboxin was0.9998,the variation coefficent was 1.42%,and the average recovery was 101.2%. Conclusions： The method has met therequirements of analysis of pesticide products and can determine carbofuran and thiram and carboxin simultaneously.
