Abstract

Systematical investigations of the chlorinated pesticides elution patterns using Bio-Beads S-X 3 gel and the binary solvent system dichloromethane/cyclohexane are discussed. Proceeding from this research a simple multimatrix method for the isolation of pesticides is described. Pesticides are extracted from the samples with dichloromethane and cleaned-up with the same solvent on Bio-Beads S-X 3 gel. In the first 100 ml of eluate the interfering matrix components are separated, while the pesticides are collected in the second cleaned-up 100-160ml fraction. The quantitative identification is performed by glass capillary gas chromatography (ECD). The recovery of chlorinated pesticides is between 90% and 100%. 1982 Springer-Verlag.
