本文叙述的是采用反相高效液相色谱法 ,以甲醇为溶剂 ,甲醇 +水 +冰乙酸为流动相 ,DOS-C18为填料和紫外检测器同柱分离测定毒·辛乳油中的毒死蜱和辛硫磷。结果表明 ,毒死蜱和辛硫磷的标准偏差分别为0.021、0.051;变异系数分别为0.21%、0.34% ;回收率分别为100.6%、99.1% ,线性相关系数分别为0.9993、0.9985。
This article describes the use of reversed-phase high performance liquid chromatography with methanol as the solvent, methanol + water + glacial acetic acid as the mobile phase, DOS-C18 as the filler and UV detector column separation and determination of poison · chlorpyrifos chlorpyrifos and symplectic Phosphorus. The results showed that the standard deviations of chlorpyrifos and phoxim were 0.021 and 0.051, respectively. The coefficients of variation were 0.21% and 0.34% respectively. The recoveries were 100.6% and 99.1% respectively. The linear correlation coefficients were 0.9993 and 0.9985.
