薄层层析——溴化法分析甲对—辛乳油中甲基对硫磷和辛硫磷

Analysis of Phoxim and Parathion-methyl by Thin-layer Chromatography-Bromination Method

介绍了用薄层层析—溴化法在一块层析板上测定辛硫磷和甲基对硫磷含量。简便 ,直观 ,无需标准品 ,标准偏差分别为 0 .0 76和 0 .0 6 7,变异系数分别为 0 .5 4%和 0 .5 4% ,回收率分别为 99.2 - 10 0 .6 % ,99.6- 10 1.0 %。

Analysis of the content of Phoxim and parathion-methyl by the TLC bromination on one thin-layer plate methods is introduced,simple accurate and doesn't need standard samples. Standard deviation,variety coefficient and average recovery are 0.076?0.54%?99.2-100.6% of Phoxim and 0.067?0.54%?99.6-101.0% of Parathion-methyl.
