| 摘要 |
The present invention relates to a process for reducing the amount of organic components in water, wherein a surface-reacted natural calcium carbonate and a hydrophobic adsorbent, selected from the group consisting of talc, hydrophobised calcium carbonate, hydrophobised bentonite, hydrophobised kaolinite, hydrophobised glass, or any mixture thereof, are brought into contact with the water to be purified, the surface-reacted natural calcium carbonate being the reaction product of a natural calcium carbonate with an acid and carbon dioxide, which is formed in situ by the acid treatment and/or supplied externally, and the surface-reacted natural calcium carbonate being prepared as an aqueous suspension having a pH of greater than 6.0, measured at 20°C. |
