25％苯甲·己唑醇可湿性粉剂的高效液相色谱分析

摘要

The quantitative analysis of Difenoconazole and Hexaconazole in 25% Difenoconazole· Hexaconazole WP was carried out by using. HPLC method. The results showed that the variation coefficients of the content of Difenoconazole and Hexaconazole were 0.36% and 0.42% , the standard deviations were 0.056 and 0.043, the average recoveries were 100. 1% and 99.9% , and the linear correlation coefficients were 0.9997 and 0.9998, respectively,It had high precision and accurancy, and it corresponded to the requirement of quantitative analysis.%采用反相高效液相色谱法,对25％苯甲·己唑醇可湿性粉剂中的苯醚甲环唑和己唑醇进行定量测定,结果表明:该方法测定的苯醚甲环唑和己唑醇的变异系数分别为0.36％、0.42％,标准偏差分别为0.056、0.043,平均回收率分别为100.1％、99.9％,线性相关系数分别为0.9997、0.9998,具有较高的精度和准确度,符合定量分析的要求.
