Preparation of Paper with Protein Separation Property Filled with Cationized Amorphous Calcium Carbonate
This study employed a liquid-phase deposition method,with calcium chloride and sodium carbonate as raw materials,and magne-sium chloride as crystalline stabilizer,to successfully synthesize amorphous calcium carbonate(ACC).Subsequently,the ACC was modi-fied by cationic agent to enhance its positive charge and dispersibility.The results demonstrated that the cationic ACC possessed outstanding adsorption capability.When the mass concentration of the cationic reagent was 2.0 mg/mL and the prepared cationized ACC was filled with 4％,the adsorption capacity of bovine serum albumin was 92 mg/g.
