摘　　要：介绍了层状双金属氢氧化物的主要制备方法,共沉淀法、水热合成法、离子交换法、结构重建法和诱导水解法等,分析了不同制备方法合成的层状双金属氢氧化物的性质,包括结晶度、分散性以及可重生性能等;总结了层状双金属氢氧化物去除溶液中金属、阴离子、有机污染物的机理和能力。对未来的研究方向进行了展望,认为研究新的合成方法,将层状双金属氢氧化物原位生在其他材料上形成新的复合材料,是今后的研究重点。The preparation methods of layered double hydroxides were briefly introduced, including coprecipitation, hydrothermal synthesis, ion exchange, structural reconstruction and induced hydrolysis. The effects of different preparation methods on the layered double hydroxides properties were also discussed, including crystallinity, dispersibility and reproducibility. The metal, anion and organic pollutants removal mechanism and capacity by layered double hydroxides in the solution were summarized. The research direction in the future was proposed, it considered that study new synthetic method to lay layered double hydroxides on other materials in situ to form new composite materials is the research priorities for the future.
