| description | The invention discloses iron and magnesium modified biochar as well as a preparation method and application thereof, and relates to the technical field of water treatment. Specifically, iron and magnesium are selected to modify biochar, iron and magnesium modified biochar is synthesized through an impregnation-pyrolysis method, the specific surface area, porosity and zate potential of the biochar can be significantly increased, iron and magnesium oxides are uniformly distributed on the surface of the biochar, the iron and magnesium composite modified biochar is reacted with phosphorus in a solution to generate complex precipitation crystals, under a wide pH range, the product is stable in performance, high in adsorption capacity, simple in modification method, low in price and high in adsorption capacity for phosphorus in a solution.
本发明公开一种铁镁改性生物炭及其制备方法和用途，涉及水处理技术领域。具体为选择铁镁对生物炭进行改性，通过浸渍-热解法合成铁镁改性生物炭，该生物炭能够显著增大生物炭比表面积、孔隙率和zate电位，铁镁氧化物均匀分布在生物炭表面，利用铁镁复合改性生物炭与溶液中的磷反应生成络合沉淀晶体，在较广的pH下性能稳定，吸附能力很强，改性方法简单，价格便宜，对溶液中的磷 |
