This paper provides a systematic methodology of the extraction problem, which may be used to establish the treatability criteria for organic priority pollutants. The treatabilities are calculated based on distribution coefficients & extraction column models in the literature. Distribution coefficients (estimated) for 2-chloronaphthalene & other pollutants in various solvents are given.
