| 摘要 |
The invention pertains to a method for removing phosphate from a phosphate-containing water fraction comprising the steps of contacting a phosphate-containing water fraction with an adsorbent, the adsorbent comprising a complex of Fe(III) and pulped plant material, the pulped plant material having a carboxylate content of at least 200 microequivalent carboxylate per gram, and withdrawing an effluent water fraction from the adsorbent. The pulped plant material preferably is a pectin-containing plant material that is obtained as waste product after withdrawal of food or feed components from fruits and vegetables, more in particular a pulped plant material derived from fruit, e.g., citrus pulp and apple pulp, or a pulped plant material derived from vegetables, e.g., beet pulp, potato pulp, chicory pulp, tomato pulp, and carrot pulp, with beet root pulp being particularly preferred. An adsorbent suitable for use in this process, and a method for manufacturing an adsorbent are also claimed. |
