Method for the separation of organochlorine residues before gas-liquid chromatographic analysis.


The adsorption characteristics of alumina and silica for column chromatography have been assessed to develop a method, using a single solvent, for the separation of seventeen organochlorine residues into four eluates prior to gas-liquid chromatographic analysis. The effects on the adsorbents of thermal activation and subsequent deactivation with water… (More)
