摘要
纳米材料由于其特有的理化性质,如强的吸附性能、高的催化效率,不仅克服了传统污染水体和污染土壤修复技术的不足,而且表现出更高的修复效率。因此,利用纳米材料对污染环境进行修复已成为当今环境领域的研究热点。本文对纳米Fe0、表面修饰的纳米材料、纳米螯合剂等纳米材料近几年在污染水体和污染土壤修复中的进展进行了归纳和总结,并且对其在环境科学与工程领域应用的研究重点进行了展望。
Nanomaterials,due to their unique physical and chemical characteristics such as strong capacity of adsorption and high efficiency of catalysis,can not only overcome many shortcomings from the conventional remediation of contaminated water and soil,but also display higher remediation efficiency. Therefore,utilizing nanomaterials to remedy contaminated environment is becoming a research hotspot. This paper summarized the research progress in the applications of nanomaterials （including nanoiron,surface-modified nanomaterials,and nanochelating agents） in remediation of contaminated water and soil,and proposed some key issues in the research and application of nanomaterials in environmental science and engineering.
