Abstract:This study employed a liquid-phase deposition method, with calcium chloride and sodium carbonate as raw materials, and magnesium chloride as crystalline stabilizer, to successfully synthesize amorphous calcium carbonate (ACC). Subsequently, the ACC was modified 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. |
