摘要
采用高效液相色谱法测定12%噻虫嗪·噻唑磷颗粒剂中噻虫嗪和噻唑磷的质量分数,使用C18反相柱和紫外可变波长检测器,以乙腈+0.3%冰乙酸水溶液为流动相,用外标法对有效成分进行分析和定量。结果表明,噻虫嗪和噻唑磷的线性相关系数分别为0.999 3和0.999 4,标准偏差分别为0.056、0.140,变异系数分别为2.68%、1.35%,平均回收率分别为100.05%、99.74%。
A method was developed for the determination of thiamethoxam ＋ fosthiazate 12% GR by HPLC on Ci8 column with variable wavelength UV detector, using acetonitrile and 0.3% acetic acid aqueous solution as mobile phase. The results showed that the linear correlation coefficients of thiamethoxam and fosthiazate were 0.999 3 and 0.999 4, the standard deviations were 0.056 and 0.140, the coefficients of variation were 2.68% and 1.35%, the average recoveries were 100.05% and 99.74%, respectively.
