Drinking water contaminated by arsenic for an extended period of time could be detrimental to the health of people. Some preliminary symptoms could be alleviated by drinking water non-contaminated. It is important to develop an arsenic removal agent with a specific property of most efficient, cost-effective and easy for operation. The results showed that the capacity of the agent developed in this study was 10 times higher for arsenic removal than other agent available. The lowest arsenic content of the treated water was 0.05 mg/L. The special function of this agent was arsenic removing without changing other components and the concentrations of other elements in the treated water. The operation and management was simple without adjusting pH of the influent and effluent water. The agent was 5 times cheaper in cost than alumina or activated carbon, because it was a reusable oxidation-catalyst. Therefore, the agent could be widely applied in drinking water plants or used as a purifier at home in the high arsenic areas.
长期饮用被砷污染的水可能对人体健康有害。一些初步症状可通过饮用未受污染的水得到缓解。开发一种具有高效、经济且易于操作等特定性能的除砷剂很重要。结果表明，本研究开发的药剂除砷能力比其他现有药剂高10倍。处理后水中的最低砷含量为0.05毫克/升。该药剂的特殊功能是除砷而不改变处理后水中的其他成分和其他元素的浓度。操作和管理简单，无需调节进水和出水的pH值。该药剂成本比氧化铝或活性炭便宜5倍，因为它是一种可重复使用的氧化催化剂。因此，该药剂可广泛应用于饮用水厂或在高砷地区用作家庭净水器。
