<p>The present invention relates to a hydrogel product for adsorption where an in water non-soluble support matrix is cross-linked with polymers which give rise to an in water swellable adsorbent. As support matrix an organic polymer or a combination of such are used, e.g. polysaccharide such as agar, cellulose, starch among other things, protein and components of protein and polysaccharide. The support matrix is substituted with a first, soluble polymer material chemically bound to the support matrix, whereupon additional polymer material are built in the primary synthesized support matrix polymer complex through different kinds of cross-links whereby optionally the support matrix is present in the form of an acid- and base-stable residue.</p> |
