摘要
水体的重金属钼污染在中国部分地区已经显现,明确钼迁移转化规律是治理钼污染的基础。在总结水体钼污染形成机制的基础上,综述了水体钼污染物迁移转化的研究进展。其中,在水体胶体对钼的吸附研究方面较深入,酸碱条件和胶体种类是钼迁移转化的主要影响因素。而目前的研究,对尾矿中不同种类原钼矿物迁移转化与环境条件相互作用的关系尚不明确。因此,解决实际钼污染问题还需更深入的系统性探索。
Heavy metal Mo pollution in water bodies has become a concern in some areas of China. The under- standing of aqueous phase migration and transformation of Mo pollutants is essential to deal with issues of Mo con- tamination. The paper presents literature reviews on the mechanism of Mo pollution, migration and transformation of Mo containing pollutants in water bodies. Detailed discussion on aqueous phase adsorption of Mo species on colloids is presented, including the effects of pH and colloid type on migration and transformation of the pollutants. Such processes have not been well accounted for in the current papers and reports. More research in interactive relation- ships between original molybdenum minerals in tailings and the environmental conditions, efficient analytic methods for Mo compounds, and technologies for removing them from water bodies are recommended to help solving the prob- lems of Mo contamination.
