【摘要】 [目的]研究高效液相色谱同时分析哒螨灵和异丙威含量的可行性。[方法]以乙腈、水为流动相,使用C18色谱柱和紫外检测器,在260 nm波长下对哒螨灵和异丙威进行反相液相色谱分离和定量分析。[结果]哒螨灵和异丙威的线性相关系数分别为0.9997和0.9995,标准偏差为0.08和0.10,变异系数为2.57%和1.09%,回收率为99.58%和99.80%。[结论]分析方法准确、简便,可以用来分析12%哒螨灵.异丙威烟剂中有效成分的含量。更多还原

【Abstract】 [aims] A hPlc method was developed for the simultaneous quantitative determination of pyridaben and isoprocarb.[Methods] The sample was separated and analyzed quantitatively on c18 column and UV detector at 260 nm,using acetonitrile and water as mobile phase by reverse phase hPlc.[Results] The results showed that the linear correlation coefficients of pyridaben and isoprocarb were 0.9997 and 0.9995.The standard deviation were 0.08 and 0.10,the variation coefficients were 2.57 and 1.09%,the average recovery rates were 99.58 and 99.80%,respectively.[Conclusions] The analysis method is accurate,simple,and suitable for the analysis of pyridaben.isoprocarb 12% FU.更多还原
