生物炭作为吸附剂对于水中的重金属、抗生素、有机污染物以及无机污染物都具有良好的处理效果;将生物炭与磁性材料结合,给予生物炭材料以磁响应特性,解决材料难回收,不易分离、损耗大等问题,并且磁性生物炭具有比表面积大、表面官能团多等优点,而以磁性生物炭为载体制备的二氧化钛光催化材料作为一种新型的环境功能材料,可以有效的提高材料的光催化活性,被广泛应用于水质污染处理过程中.本文对该复合材料的制备方法、性质等方面进行的综述,为后来者研究探索高效、节能、环境友好型的水体污染物处理材料提供了一定的方向以及理论依据.

Biochar as adsorbent has good treatment effect on heavy metals, antibiotics, organic pollutants and inorganic pollutants in -water. The combination of biochar and magnetic material gives biochar material a magnetic response characteristic, yvhich solves the problems of difficult recovery, difficult separation, large loss and the like of the material. Magnetic biochar has the advantages of large specific surface area, multiple surface junctional groups and the like. As a new type of environmental Junctional material, titanium dioxide photocatalytic material prepared by taking magnetic biochar as a carrier can effectively improve the photocatalytic activity of the material and is widely used in the water pollution treatment process. The preparation methods and properties of this composite material are summarized, which provides a certain direction and theoretical basis for the research and exploration of high-efficiency, energy-saving and environment-friendly water pollutant treatment materials for the latecomers.
