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.
