ADSORPTION OF ORGANIC MATERIAL IN AQUEOUS MEDIUM AND/OR REDUCTION OF THE AMOUNT OF ORGANIC MATERIAL IN AQUEOUS MEDIUM BY USING COLLOIDAL PRECIPITATED CALCIUM CARBONATE

摘要

To provide alternative materials that effectively adsorb and/or reduce the amount of organic material in an aqueous medium produced by a papermaking or pulping process.SOLUTION: A specific surface area of at least 5.0 m/g of colloidal precipitated calcium carbonate (cPCC) measured using nitrogen and the BET method to adsorb at least one organic material in an aqueous medium and/or reduce the amount of at least one organic material in an aqueous medium.SELECTED DRAWING: Figure 6
