摘要
传统工艺难以从水溶液中回收稀土离子,造成稀土资源的严重浪费。改性生物炭因来源广泛、制备简单、成本低廉且环境友好使其被应用于水处理领域。吸附法是有前途的回收方法,总结了生物炭的原料性质及改性方法,探讨了改性生物炭对水溶液中稀土离子的吸附机理及应用研究,最后展望了其领域未来的发展方向。
Traditional processes are difficult to recover rare earth metal ions from aqueous solution,resulting in a serious waste of rare earth resource.Modified biochar has been applied in the field of water treatment due to its wide availability,simple preparation,low cost and environmental friendliness.Adsorption method is a promising method for recovering rare earth metal ions from wastewater.This paper summarizes the properties of raw materials of biochar and the modification methods for biochar,explores the mechanism for adsorption of rare earth metal ions in aqueous solution by modified biochar and the corresponding application research,and looks forward to the development directions of this field in the future.
