In recent years, layered double hydroxide (LDH) has attracted much attention in the field of water treatment because of its special layered structure and highly controllable performance. In addition to being used for heavy metal adsorption, LDH also shows unique advantages in the adsorption of dyes. However, due to the shortcomings of single LDH, such as poor acid-base resistance, less surface functional groups, poor chemical stability, which restrict its application in dye wastewater treatment. To this end, more and more researchers through the modification of LDH to improve the adsorption properties of materials. In this paper, the preparation and modification methods of LDH materials are summarized, and their advantages and disadvantages are compared. Secondly, the removal effect and adsorption mechanism of ion in dye wastewater by modified LDH materials are introduced, at the same time, the influence of different environmental conditions (pH, contact time, amount of adsorbent, etc.) on the adsorption performance is analyzed. Finally, the application status of modified LDH materials is summarized, and its future development is prospected.
