A simple method is described for the simultaneous quantitative determination of captan [N-(trichloromethylthio)-3a,4,7,7a-tetrahydrophthalimide] and captafol [N-(1,1,2,2-tetrachloroethylthio) -3a,4,7,7a - tetrahydrophthalimide] in apples and potatoes. The fungicide residues are extracted with acetonitrile, partitioned into a solution of methylene chloride in petroleum ether, separated from each other and the co-extractives on a thin layer chromatographic plate impregnated with aluminum chloride, sprayed with sodium chlorate, and heated. The fluorescence is then measured directly from the chromatogram. Recoveries were greater than 90% in the test crops at the 0.2 ppm level.
本文描述了一种同时定量测定苹果和土豆中克菌丹[N-(三氯甲基硫代)-3a,4,7,7a-四氢邻苯二甲酰亚胺]和灭菌丹[N-(1,1,2,2-四氯乙硫基)-3a,4,7,7a-四氢邻苯二甲酰亚胺]的简单方法。将杀菌剂残留物用乙腈提取，分配到二氯甲烷的石油醚溶液中，在涂有氯化铝的薄层色谱板上彼此分离并与共提取物分离，喷上氯酸钠并加热。然后直接从色谱图中测量荧光。在0.2 ppm水平下，测试作物中的回收率大于90%。
