| description | PURPOSE:To adsorb proteins from a solution suitably and eliminate an odor of carbon and resin therefrom by forming a protein adsorbent wherein at least one metal selected from the group consisting of silver, gold and copper is supported on a silica base material. CONSTITUTION:A metallic salt aqueous solution is prepared of an inorganic acid salt of silver, gold and copper such as nitrate, sulfate, hydrochloride and phosphate thereof or an organic acid salt of the same such as their acetate and naphthenate. A silica base material comprising a fine silica powder or a silica in the form of sheet is immersed in this metallic salt aqueous solution with agitation. Then, the silica base material is separated from the solution, washed with water, if needed, and dried to obtain a protein adsorbent supporting the metals. It is preferable that the silica base material should support 0.1 to 15wt.% of the metals. The obtained protein adsorbent is capable of adsorbing proteins in solutions suitably. A silica base material in the form of fine silica powder supports metals well and can be added to a fiber or a sheet amenable to the processing wherein the adsorbent is molded into a shape handy for the use. |
