摘　　要：采用高效液相色谱法,以乙腈+水(体积比65∶35)为流动相,使用不锈钢柱和SPD-20A UV检测器,在240 nm波长下对40%丁醚·噻虫啉悬浮剂进行分离和定量分析。结果表明,噻虫啉和丁醚脲的线性相关系数分别为0.997 0和0.993 0,相对标准偏差分别为0.22%和0.18%,平均回收率分别为97.89%和99.42%。方法的精密度和准确度良好,可用于复配产品中噻虫啉和丁醚脲的分析检测。A method was established to separate and quantitative analysis of diafenthiuron·thiacloprid 40%SC by HPLC,using acetonitrile+water(volume ratio of 65:35)as mobile phase,on stainless steel column and SPD-20A UV detector,at 240 nm.The results showed that the linear correlation coefficients of thiacloprid and diafenthiuron were 0.9970 and 0.9930,the relative standard deviations were 0.22%and 0.18%,and the average recoveries were 97.89%and 99.42%,respectively.The method was precise and accurate,it could be used for the determination of thiacloprid and diafenthiuron in compound products.
