| 摘 要： | 广泛存在于地下水中的各种有机污染物严重影响着水资源的安全利用,常见的水处理工艺对持久性有机污染物去除效果不够理想。近年来,天然含铁矿物作为催化剂,催化过氧化氢的化学治理方法对各种有机污染物去除效果显著。概述近年来主要含铁矿物、负载型矿物和纳米矿物材料催化过氧化氢在地下水有机污染去除中的应用,探讨了该领域的发展现状和存在问题,并对其应用前景进行展望。认为天然矿物材料具有成本低、在地壳中含量高、环境友好等特点,可用于多种有机污染物的去除与降解。但处理过程中,天然有机质的作用、纳米矿物材料的毒性和地球化学归宿问题应该做进一步研究。

| Abstract: | The safe utilization of water resources is a problem of much concern because there are many organic pollutants in groundwater. Traditional water treatment process for the removal of persistent organic pollutants shows unsatisfing effect. In recent years, the use of natural iron-bearing minerals as catalysts is a promising technique for the remediation of groundwater and industrial effluents. This review summarizes the recent application of iron-bearing minerals, clay-supported minerals and nano-scale minerals as active catalysts with hydrogen peroxide for groundwater remediation. The status of problems and development is also discussed in this paper. Studies have shown that these iron-bearing minerals used in pollutants removal are very attractive for their low cost, abundance, and environmental benign characteristics in the earth's crust; nevertheless, the influence of the natural organic matters, the uncertainties of the health impacts and the environmental fate of these particles deserve further investigation before their widespread application. |
