Preparation method of amorphous iron oxyhydroxide and recovery method after organic matter adsorption |
| abstract |
The invention discloses a preparation method of amorphous FeOOH and a recovery method after organic matter adsorption, which improves the preparation efficiency of amorphous FeOOH. The hydroxyl ferric oxide after adsorbing the organic matters is effectively recycled, the nanometer alpha ferric oxide with the photocatalysis effect is obtained after calcination, and due to the existence of the organic matters, the crystal grains of the prepared nanometer ferric oxide are thinner than those of the nanometer ferric oxide directly prepared from amorphous hydroxyl ferric oxide, the surface of the nanometer ferric oxide has more active points, and the catalysis effect is better. |
