摘要
介绍了砷污染的来源以及危害,传统处理方法的优劣及其应用限制和最新低成本脱砷吸附剂的研究进展。在水污染领域,低浓度污染水体一直都是较为棘手的问题,因为体量巨大无法统一处理。吸附技术,尤其是低成本吸附剂对于此类体量巨大的低浓度砷污染水体的脱砷具有极其重要的作用。从吸附剂原材料、吸附容量以及吸附等温线拟合效果方面,综述了低成本吸附剂吸附脱砷的最新研究进展,并指出了其在实际应用上的不足,探讨了低成本脱砷吸附剂的未来研究方向。
This paper reviews the source and harm of arsenic pollution,along with the advantage and disadvantage of traditional arsenic treatment technology and novel low-cost arsenic adsorbents.Low-concentration arsenic contaminated water has been a difficult problem,because with too high a volume,it cannot be treated uniformly.Adsorption technology,especially that of low-cost adsorbents,plays an important role in arsenic removal from large volume water contaminated by low-concentration arsenic.This paper summarizes the current research progress of low-cost arsenic adsorbents from the aspects of raw materials,adsorption capacity,and adsorption isotherm fitting results,and points out its drawback in application.Finally,the future research direction of low-cost arsenic adsorbents is prospected.
