Effect of zeolitic imidazole framework (ZIFs) shells of core-shell microspheres on adsorption of Roselle red dye from water

A series of new adsorbents with core-shell structure, CSS-ZIFs were successfully prepared and the adsorption properties for Roselle red were investigated. The π-π attraction and cation-cation repulsion between different ZIF shells and Roselle red molecules affects the adsorption performance.60
