Abstract：
Arsenic poisoning of groundwater is one of the most critical environmental hazards on Earth. Therefore, the practical and proper treatment of arsenic in water requires more attention to ensure safe drinking water. The World Health Organization (WHO) sets guidelines for 10 μg/L of arsenic in drinking water, and direct long-term exposure to arsenic in drinking water beyond this value causes severe health hazards to individuals. Numerous studies have confirmed the adverse effects of arsenic after long-term consumption of arsenic-contaminated water. Here, technologies for the remediation of arsenic from water are highlighted for the purpose of understanding the need for a single-point solution for the treatment of As(III)-contaminated water. As(III) species are neutral at neutral pH; the solution requires transformation technology for its complete removal. In this critical review, emphasis was placed on single-step technologies with multiple functions to remediate arsenic from water.
摘要：
地下水砷中毒是地球上最严重的环境危害之一。因此,对水中砷的实际和适当处理需要更多的关注，以确保安全的饮用水。世界卫生组织（WHO）制定了饮用水中10μg/L砷的准则，直接长期暴露于超过该值的饮用水中的砷会对个人造成严重的健康危害。大量研究证实了长期消耗砷污染水后砷的不利影响。这里,强调了从水中修复砷的技术，以了解对处理As（III）污染水的单点解决方案的需求。由于（III）物种在中性pH下是中性的；该溶液需要转化技术才能完全去除。在这次重要的审查中，重点放在具有多种功能的单步技术上，以从水中修复砷。
