A hydrogel product for adsorption wherein water non-soluble support matrix is cross-linked with polymers which give rise to a water swellable adsorbent. As support matrix an organic polymer or a combination of such are used; e.g. polysaccharides such as agar, cellulose, or starch, proteins and components of proteins and polysaccharides. The support matrix is substituted with a first soluble polymer material chemically bound to the support matrix, whereupon additional polymer materials are built into the primary synthesized support matrix polymer complex through different kinds of cross-oinks whereby optionally the support matrix is present in the form of an acid- and base-stable residue.
