Extractants for organochlorine insecticides and polychlorinated biphenyls from water.
A reversed liquid-liquid partition system prepared from Chromosorb W, n-undecane and Carbowax 4000 monostearate was shown to be suitable for extracting organochlorine insecticides and polychlorinated biphenyls (PCBs) from water (with the exception of Aroclor 1260). The performances of the partition system, Amberlite XAD-4, porous polyurethane foam and the solvent extraction technique when applied to the analysis of four environmental water samples were comparable (except for Aroclor 1260).
