Abstract
The systematic separation and identification of many kinds of pesticides were attempted by a combination of column, thin-layer and gas chromatography (GLC). Fifteen pesticides in the fourth division1)-e. g., trietazine, prometryne, propazine, atrazine, BPMC, swep, terbam, carbanolate, captan, etc. were eluted into two fractions by column chromatography. Furthermore, these pesticides were separated from each other and determined by GLC with ECD and FID, after divided into five groups by thin-layer chromatography (TLC). Most of these pesticides were more than 85% recovered.
