Polychlorinated biphenyls can be extracted from fish oils with supercritical carbon dioxide at quite modest temperature and pressure with little yield loss of the fish oils. The distribution coefficient, viz, the ratio of the concentration of polychlorinated biphenyls in the carbon dioxide and fish oil phases, respectively, was measured to be about 0.01 (wt basis). The selectivity of carbon dioxide for polychlorinated biphenyls was found to be very high, about 13 at a concentration of about 10 ppm.
