摘要
采用高效液相色谱法,以甲醇+水=80+20(V/V)为流动相,使用C18色谱柱,在220nm波长下对1%二嗪磷·噻虫嗪颗粒剂样品中的噻虫嗪和二嗪磷进行分离和定量分析。结果表明:噻虫嗪和二嗪磷的线性相关系数分别为0.9994、0.9997;标准偏差分别为0.49%、0.34%;变异系数分别为2.36%、0.42%;平均回收率分别为99.73%、99.84%。该方法操作简单、快速、准确,适用于1%二嗪磷·噻虫嗪颗粒剂样品的定性和定量分析。
In this paper,diazinon and thiamethoxam in 1%granule formulation were separated and quantified by HPLC method using methanol+water=80+20(v/v)as mobile phase and C18 chromatographic column under 220 nm wavelength.The results showed that the linear correlation coefficient of 0.9994 and 0.9997,the standard deviations of 0.49%and 0.34%,the variation coefficients of 2.36%and 0.42%and the average recoveries of 99.73%and 99.84%were obtained for thiamethoxam and diazinon respectively.The method was simple,rapid and accurate enough for the qualitative and quantitative analysis of diazinon and thiamethoxam 1%granule sample.
