摘要：
Cryotropic gel formation was used to obtain composite chitosan-containing macroporous cryogels derived from polyvinyl alcohol. The adsorption properties of these cryogels were studied relative to the textile dye, acid yellow K. The effects of the physicochemical parameters of the adsorption process as well as of the composition and structure of the cryogel on the adsorption kinetics and equilibrium adsorption were studied. Feasibility was demonstrated for regeneration of the adsorbent and multiple adsorption without change in the adsorption capacity of the composite cryogel.
