黄铁矿去除水中砷/铬性能和机理研究进展

Advances in the Performance and Mechanism of Arsenic/Chromium Removal from Water by Pyrite

重金属对水体造成的污染严重威胁着人类社会的健康发展。开发高效、绿色、低成本的天然矿物基材料是修复砷、铬污染水体的潜在有效措施。本文重点阐述了黄铁矿在砷、铬废水处理中的应用现状,剖析了黄铁矿去除水中砷、铬的相应机制。未来,关于黄铁矿的应用,相关人员应深入考虑其长期稳定性和安全性,可通过改性或研发纳米黄铁矿以显著提高废水处理效率。

Water pollution caused by heavy metals is a serious threat to the healthy development of human society.The development of efficient,green and low-cost natural mineral-based materials is a potentially effective measure to remediate water polluted by arsenic and chromium.The current status of pyrite in the treatment of arsenic and chromium wastewater was highlighted,and the corresponding mechanism of pyrite in removing arsenic and chromium from water was revealed.In the future,the application of pyrite should be considered in depth for its long-term stability and safety.The efficiency of wastewater treatment could be significantly improved by modifying or developing nano-pyrite.
