A kind of carbonate modified diatomite adsorbent and its preparation method and application |
| abstract |
This paper discloses a preparation method of a La-modified diatomite phosphorus removal adsorbent, which uses diatomite as a porous support to make the generated lanthanum carbonate nano-sized, effectively improving the adsorption capacity of phosphorus, and at a suitable pH The adsorption capacity of modified diatomite for phosphorus is greatly improved within the range. According to the order of adding the reactants of the present invention, the formation process of the lanthanum carbonate-based compound can be controlled, so that the phosphorus adsorption site on the surface of the prepared adsorbent material is more active, and it is easier to achieve specific binding with phosphate, and will not be affected by competing ions. The adsorbent solves the problem of alkaline effluent after the traditional diatomite-supported metal hydroxide for phosphorus removal, and has a good application prospect. |
