Abstract: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.
Keywords:pyrite; heavy metal contamination; water treatment technology; arsenic; chromium
