农林废弃物吸附废水中Cd^2+的研究进展

Research Progress on Adsorption of Cd^2+in Wastewater by Agroforestry Wastes

农林废弃物来源广泛、价格低,用于含镉废水处理,可实现资源的综合利用,具有良好的前景。本文从天然材料吸附剂、改性材料吸附剂以及生物炭吸附剂3个方面综述近年来国内外利用农林废弃物作为吸附剂处理废水中镉离子的研究进展。

Agricultural and forestry waste has a wide range of sources and low price.It can be used in the treatment of wastewater containing cadmium,which can realize the comprehensive utilization of resources and has a good prospect.In this paper,the research progress of using agricultural and forestry wastes as adsorbents to treat cadmium ion in wastewater at home and abroad in recent years was reviewed from natural material adsorbent,modified material adsorbent and biochar adsorbent.
