A stable HOF-embedded alginate hydrogel membrane for selective adsorption of cationic dyes†
Abstract
Targeted at organic dye pollutants, a stable HOF was combined with an alginate (SA) hydrogel to enhance the affinity for cationic dyes. The as-obtained HOF@SA membrane (weight ratio: 1/1) shows a high adsorption capacity (729.21 mg gā1), adsorption selectivity and good recycling performance towards methylene blue.
