砷污染已成为世界性的环境问题。天然沃茨中危险的砷浓度威胁着数百万人的健康，这一点已受到极大关注。在已开发的各种去除水中砷的技术中，使用吸附技术被认为是一种普遍的方法，因为吸附方法通常具有高去除效率和操作方便的优点。近年来，层状双氢氧化物（LDHs）由于其亲水性和阳离子层状结构而成为除砷的主要候选物。LDH除砷的研究主要集中在（1）LDH的合成方法和组成的影响，（2）LDH的粒径的影响，（3）LDH中Mg/Al比的影响，（4）LDH基杂化物，（5）与其它阴离子的竞争。本文综述了目前可用的文献，重点是使用LDHs去除砷的上述五个部分。此外，在这一概述的基础上，最后一节将提出今后工作的研究努力。本文对这一领域的主要研究成果进行了总结，并对今后的发展方向进行了展望。本文提供了一个综述目前可用的文献，重点是使用LDHs去除砷。
Arsenic pollution has become a worldwide environmental concern. Dangerous arsenic concentrations in natural waters threaten the health of millions of people, and this has received significant attention. Among the various technologies that have been developed for arsenic removal from water, the use of adsorption technology is considered to be a prevailing method, because the adsorption approach usually has high removal efficiency and the advantage of convenience of handling. In recent years, layered double hydroxides (LDHs) have become prime candidates for arsenic removal, due to their hydrophilic nature and cationic layered structures. Research on arsenic removal using LDHs is mainly focused on (1) the influence of the synthesis method and composition of the LDH, (2) the influence of the particle size of the LDH, (3) the influence of the Mg/Al ratio in LDHs, (4) LDH-based hybrids and (5) the competition with other anions. This paper provides a review of the currently available literature focusing on arsenic removal using LDHs for the five parts mentioned above. In addition, based on this overview, a closing section will suggest research efforts for future work. It is expected that this review will provide a summary of the main research in this area, and will also shed light on the direction of future development. This paper provides a review of the currently available literature focusing on arsenic removal using LDHs.
