介绍了用薄层层析—溴化法在一块层析板上测定辛硫磷和马拉硫磷含量。简便、直观、无需标准品,标准偏差分别为0.032%和0.17%,变异系数分别为0.21%和0.85%,回收率分别为99.1%—100.6%、99.0%—100.4%。
The determination of phoxim and malathion on a chromatographic plate by thin-layer chromatography-bromination is described. The standard deviation was 0.032% and 0.17% respectively. The coefficient of variation was 0.21% and 0.85% respectively. The recoveries were 99.1% -100.6% and 99.0% -100.4% respectively.
