功能化生物炭吸附水中无机污染物的研究进展

生物炭作为一种多孔材料可用于污染水体修复,但生物质直接制备的原始生物炭通常吸附能力有限且回收再利用和固液分离困难。以原始生物炭为基础,通过各种改性技术制得的功能化生物炭在水处理领域表现出巨大的应用潜力。归纳和分析了近年来功能化生物炭对水体无机物污染物的吸附研究,总结了吸附水体无机污染物的功能化生物炭的制备方法、吸附性能、机制和影响因素。在此基础上,从实际应用、经济和技术可行性等方面提出了今后研究的重点。

Adsorption of Inorganic Contamination in Aqueous Solution with Multifunctionalized Biochar: a Review

Biochar, as a porous material, could efficiently remove a variety of pollutants from water, however, the practice application of prinstine is generally limited by the problems of low adsorption capability, difficult recycle generation and separation from water. The multifunctionalized biochar produced by various modified technologies exhibits a great potential in decontamination of water. In this study, the research about inorganic pollutants adsorption of multifunctionalized biochar were generalized, and the preparation methods of multifunctionalized biochar as well as adsorption capability, mechanism and influencing factors to remove inorganic pollutants in water were mainly summarized. Additionally, the future research emphasis and direction of multifunctionalized biochar, in terms of practical application, economic and technical feasibility, were suggested.
