| 中文摘要: |
| 自然环境中的砷污染问题被认为是全球最严重的环境威胁之一，人类长期暴露于含砷饮用水环境中会引起各种疾病的发生，因此，开发经济有效的除砷技术一直是砷污染治理领域的研究热点。铁基水处理材料由于其对砷的良好亲和力、表面反应活性强、价廉易制、便于回收等特点，一直备受关注。本文综述了近年来不同铁基水处理材料如铁（氢）氧化物、纳米零价铁、铁基多金属氧化物复合材料除砷技术的研究进展，论述了铁基水处理材料对水相中砷去除的影响因素及机理；同时，对影响铁基水处理材料砷解吸的因素和毒性评估研究进行了总结；指出了目前铁基水处理材料砷污染去除技术研究中存在的主要问题，并对水相砷污染去除技术研究中值得关注的重要发展方向进行了展望。 |
| 英文摘要: |
| Arsenic in the natural environment is considered as one of the most serious environmental threats in the world. Long-termexposure to arsenic from drinking water can cause various diseases. Therefore, there is an urgent need to develop economically effective arsenic removal technology. Iron-based water treatment materials have attracted more attention on arsenic removal due to its good affinity to arsenic, strong reactivity on the surface, low cost, easy preparation and recycling. This paper summarizes the progress in arsenic removal technology by iron-based materials, such as ferric (hydr) oxide, zero-valent iron, iron-based multi-mental oxide and their composites. Possible influence factors and mechanisms of arsenic removal in aqueous solution by different iron-based water treatment materials were discussed in details. At the same time, the influence factors of arsenic desorption and the toxicity assessment of the above mentioned materials were summarized. Finally, the main problems about arsenic removal existed in present research are put forward. The prospects for the further development of iron-based water treatment materials for arsenic removal are also discussed. |
