Abstract

PURPOSE:To obtain a chitosan carrying material useful as various carriers, readily providing a shape of necessary size, by supporting chitosan at least on the surface of a porous substrate. CONSTITUTION:Usually 1-40wt.% chitosan is supported at least one the surface of a porous substrate (e.g. silica gel, alumina gel, silica alumina gel, porous glass or granular active carbon) having preferably 20-5,000Angstrom average pore diameter and 0.5-2.0cc/g average pore volume to give a chitosan carrying material. As the supporting method, for example, water-glass and sulfuric acid in a desired ratio of silicon are blended into pH 1.5-2 to form acidic sol, which is then cooled to -1-5 deg.C to precipitate salt cake and impurities. The sol is then mixed with chitosan, stirred in a nonpolar liquid medium containing a surface active agent is gelatinized with ammonia.
