摘要
介绍了溶剂热法、溶胶-凝胶法、共沉淀法、微乳液法这4种磁性纳米材料的主要制备方法,阐述了各个方法对磁性纳米材料的制备过程以及对重金属离子的吸附作用并探究其吸附机理。为找到更加经济型、高效型及环境友好型的重金属吸附材料提供参考依据,对进一步提高磁性材料对重金属的吸附效率做出展望。
The preparation methods of magnetic nanomaterials are introduced,including solvent thermal method,solgel method,co-precipitation method and micro-emulsion method. The effects of four kinds of methods on the preparation process of magnetic nanomaterials and adsorption of heavy metals are described. The adsorption mechanism is also discussed. It provides a reference to design more economical,efficient and environmentally friendly heavy metal adsorption materials and gives a broad prospect of improving the efficiency of magnetic materials for adsorption of heavy metals.
