Thin-layer chromatography (TLC) of fourteen important organophos-phorus, organochlorine, and pyrethroid pesticides has been performed on mixed stannic oxide-silica gel G layers. The results of these studies reveal that this new combination has promising potential for separation of pesticides. RF values of these pesticides have been determined after development with a variety of mixed aqueous and organic mobile phases. Several important and difficult separations of synthetic pesticide mixtures were achieved on the basis of the different transport of the pesticides by the different mobile phases. The practical utility of these separations has been demonstrated by quantitative determination of monocrotophos, dimethoate, and malathion in soil samples.
