Abstract

For the quantitative selective removal or/and preparative isolation of tumour necrosis factor (TNF) or/and lipopolysaccharides from aqueous liquids, in particular blood, plasma or serum, the aqueous liquid is passed over an adsorption material which consists of a porous supporting material to which functional groups made of synthetic or/and semisynthetic or/and natural polyanion chains and namely in a linear or branched form, are covalently bound and if desired, the molecules chromatographically separated in this way are eluted from the adsorption material using a saline solution. A device according to the present invention for the extracorporeal removal of tumour necrosis factor and/or lipopolysaccharides (LPS) from aqueous liquids, in particular blood, plasma or serum, consists of a cylindrical housing which is filled with an adsorption material which consists of a porous supporting material to which functional groups made of synthetic or/and semisynthetic or/and natural polyanion chains and namely in a linear or branched form, are covalently bound and is provided with covers at its front ends which each have a central inlet and outlet.
