摘要
黄铁矿(FeS_(2))因其资源丰富、价格低廉和具有可作为潜在的非均质Fenton试剂受到广泛关注。但FeS_(2)具有比表面积小、Fe(Ⅱ)/Fe(Ⅲ)循环途径较少、循环使用次数低等缺陷,无法进一步满足实际应用的要求。本文综述了常见的改性FeS_(2)非均相类Fenton优化技术,主要包括引入外场、改变催化剂载体、非均相Fenton反应过程中引入其他物质等三大方向并分析了它们的优缺点,以及FeS_(2)非均相Fenton的机理和应用,展望了改性FeS_(2)非均相Fenton反应未来的重点研究方向,为进一步完善改性FeS_(2)非均相类Fenton技术优化方案,开发出低成本、高性能的非均相Fenton水处理方向提供新的思路。
Pyrite(FeS_(2))has attracted wide attention because of its abundant resources,low price and potential as a heterogeneous Fenton reagent.However,FeS_(2)has the disadvantages of small specific surface area,low Fe(Ⅱ)/Fe(Ⅲ)cycles,and low cycle times,which cannot further meet the requirements of practical applications.In this review,the common optimization technology for modified FeS_(2)heterogeneous Fenton are summarized,mainly including introducing external fields,changing the catalyst support,and adding other substances in the heterogeneous Fenton system.The advantages and disadvantages of these technologies are also analyzed,as well as the mechanism and application of heterogeneous Fenton.The future key research directions of the modified FeS_(2)heterogeneous Fenton reaction are further suggested.The review provides new ideas to further improve the modified FeS_(2)heterogeneous Fenton,and to develop a low-cost,high-efficiency heterogeneous Fenton water treatment technology.
