近年来纳米材料受到越来越多的关注,由于其纳米尺寸效应,纳米材料在环境修复、医药、生物工程等各个领域都有广泛的应用。纳米材料具有大的比表面积、高表面结合能等优异特性,这使其在重金属吸附领域的应用受到极大的关注。金属硫化物纳米材料属于其中一类,其作为吸附剂具有吸附速度快、吸附容量高、吸附产物稳定等优良特性,对水体和土壤基质中的重金属离子、放射性元素和有机物等表现出良好的吸附性能,具有潜在的研究和应用价值。本文综述了国内外几类金属硫化物纳米材料在吸附领域的研究进展,包括Zn S、铁硫化物、Mo S2、Cu S和其他金属硫化物及其相关复合材料,并对其未来的发展方向进行了展望。
In recent years, nanomaterials have received more and more attention. Because of their nano-size effect, nanomaterials are widely used in various fields such as environmental remediation, medicine and bioengineering. Nanomaterials have excellent properties such as large specific surface area and high surface binding energy, which make their applications in the field of heavy metal adsorption receive great attention. As one kind of metal sulphide nanomaterials, it has the advantages of fast adsorption rate, high adsorption capacity and stable adsorption products as adsorbent. It shows good adsorption to heavy metal ions, radioactive elements and organic compounds in water and soil matrix Performance, with potential research and application value. This review summarizes the research progress of several metal sulfide nanomaterials at home and abroad in the field of adsorption, including Zn S, iron sulfide, Mo S2, Cu S and other metal sulfides and their related composites, and its future development direction Prospects.
