the invention relates to an adsorbent material , a method for cleaning blood and plasma and purifying albumin , and to a method for producing said adsorbent material . the inventive adsorbent material is embodied in the form of a highly cross - linked and porous spherical divinylbenzene copolymer which contains from 4 to 30 weight % of an imidazole derivative and at least 50 weight % of divinylvenzene incorporated by radical polymerization in the presence of air and / or oxygen . said adsorbent material is embodied in such a way that it is biocompatible and suitable for removing free and albumin - bound toxic substances , drugs , pharmaceutical products , endogenic and exogenic toxins from blood , plasma , and external albumin circuits at a high rate and efficiency . the material is used in particular for adsorbing bilirubin and bile acids and is produced by suspension polymerization .
