粘土矿物对水中Pb^(2+)的处理技术研究进展

Research Evolvement of Treatment Technology of Pb^(2+) in Water with Clay Mineral

天然或改性粘土矿物对水中重金属离子具有良好的吸附作用,将其用于水中Pb2+的去除是目前水处理研究的热点。本文在介绍凹凸棒土、膨润土、硅藻土、海泡石这四种粘土矿物的结构和性质的基础上,对其在水中Pb2+处理方面的技术研究进展进行了综述,并对其应用前景进行展望。

Inartificial or changed clay minerals had good adsorption capacity with heavy metal in water. It was a research hotspot in the treatment of Pb^2＋ in water. Structure and character of attapulgite, bentonite, diatomite and sepiolite were introduced in the paper. The research evolvement of clay mineral in water＇ s Pb^2＋ treatment was summarized. In the end, the prospect of clay minerals＇ development was put forword.
