摘    要:综述了我国利用天然矿物治理重金属废水方面的研究新成果。天然铁的硫化物、天然铁锰的氧化物、方解石与磷灰石等具有良好的表面吸附与氧化还原化学活性;不同介质中它们能不同程度地表现出对Cr^6 、Pb^2 、Hg^2 、Cd^2 等重金属离子的吸附作用,可广泛用于重金属废水处理。矿物吸附重金属离子机理的研究表明,矿物对重金属的吸附是矿物表面与无机重金属离子之间的表面作用过程,包括矿物表面功能基与重金属离子的配位反应、矿物表面氧化还原反应和沉淀转化作用,以及矿物表面离子交换吸附作用等。

关 键 词:研究进展  治理  重金属离子  重金属废水处理  矿物表面  展望  国内  氧化还原反应  吸附作用  Cr^6+  Pb^2+  Hg^2+  Cd^2+  天然矿物  化学活性  表面吸附  矿物吸附  作用过程  配位反应  转化作用  离子交换  新成果  硫化物  天然铁  氧化物

Abstract:Based on the previous research data, the latest research achievements on the treatment of heavy metal polluted wastewater by using natural minerals in China are summarized. Natural Fe-bearing sulfides, ferromanga-nese oxides, calcite and apatite can adsorb some heavy metal ions such as Cr6+ , Pb2+, Cd2+ , Hg2+ in various kinds of chemical conditions because of their good surface adsorption capability and redox chemical activity. Therefore, these natural minerals can be widely used to treat heavy metal polluted wastewater. The study on the adsorption mechanism of heavy metal ions by natural minerals shows that the adsorption of heavy metal ions by natural minerals is a process of the surface interaction between minerals and heavy metal ions. This process includes coordination reaction between functional groups in minerals surface and heavy metal ions, redox reaction, precipitation and tran-sition, and ions exchange adsorption on mineral surfaces.
Keywords:environmental mineralogy  heavy metal wastewater  research progress and prospects
