Abstract Dye-containing industrial wastewater is constantly harmful to the ecosystem and human health. How to quickly and effectively remove dyes from water to purify the environment has become the focus of current research. A fast and efficient method was proposed to prepare the composite adsorbents by loading two component gelator on the surface of the melamine sponge for the first time. The adsorption material can selectively adsorbe cationic dyes, and adsorption of rhodamine 6G is as high as 711.75 mg·g-1. Because of the high porosity and specific surface area of melamine sponge, MS-AO6S can quickly complete the static adsorption process within 6 h, demonstrating the excellent adsorption performance. The composite can also be used for dynamic adsorption of dyes, which is of great significance for its further practical application.
