Abstract

The selective purificn. of a body fluid contg. toxic prods., e.g. a blood ultrafiltrate or the blood of a sick person, involves the use of liq. membranes forming the continuous water-insol., organic phase of an emulsion. This organic phase contains surface-active agents and a water-insol. chemical carrier which can react reversibly with the toxic prods. to give a water-insol. reaction product (X) which diffuses to the interior aq. phase of the emulsion. The aq. phase contains substances which favour decomposition of prod. X into (i) the chemical carrier, which remains in the organic phase; and (ii) the toxic prods. which disperse preferentially in the aq. phase. The aq. phase also contains substances which can combine irreversibly with the toxic prods. to form mols. which do not diffuse back into the organic phase. The toxic prods. are present in the body fluid at abnormally high concn., following irregular functioning of the organism caused by physiologically or by external physical means (e.g. burns, radiation, intoxication).
