马拉硫磷的化学名称为0,0-二甲基-S-二硫代磷酸酯,是一种广谱性杀虫剂,广泛用于害虫防治.为了了解马拉硫磷在水稻上的残留情况,制定施药至收获的安全间隔期,我们于1979年开展了马拉硫磷在晚稻上的残留研究,现将结果报道如下:分析方法采用薄层层析荧光分析法,显色剂为氯化钯——钙黄绿素。氯化钯——钙黄绿素内络合物在有马拉硫磷的情况下,钙黄绿素游离出来,在紫外灯下可观察到农药荧光斑 The chemical name of malathion is 0,0-dimethyl-S-phosphorodithioate, a broad-spectrum insecticide that is widely used in pest control. In order to understand the effect of malathion on rice Residues, the development of pesticides to harvest safety interval, we carried out in 1979 Malathion residues in late rice research, the results reported below: Analysis methods TLC analysis of fluorescence, color reagent Palladium chloride - calcein. Palladium chloride - calcein internal complex In the case of malathion, calcein free out under the UV light can be observed in the fluorescent spots of pesticides
