This work addresses the obtaining and characterization of alginate-guar gum matrix, cross-linked with epichlorohydrin in the presence of different flexible chain polymers: polyvinyl alcohol, polyvinyl pyrrolidine and Pluronic® F68. These matrixes were used for the adsorption of chymotrypsinogen and showed an increasing uptake in presence of the flexible chain polymer in the sense: noneâ¯<â¯Pluronic 68â¯<â¯polyvinyl pyrrolidineâ¯<â¯polyvinyl alcohol. The adsorption process was found to follow a first order kinetics model and was not influenced by the polymer type. It was found that Freundlich model was more suitable for our data. Polyvinyl alcohol and polyvinyl pyrrolidine addition increase the adsorption capacity of the original bed due to an increment in the rigidity of the gel caused by the formation of hydrogen bound between the polysaccharides and synthetics polymers.
