摘要

Industrial wastewater has become one of the main factors affecting human health, and wastewater purification has become an important subject of academic research. Therefore, we report a Uio-66/cellulose composite hydrogel with the advantages of simple preparation, excellent adsorption performance, and high adsorption efficiency. Cellulose hydrogels have the characteristics of simple preparation and excellent adsorption. As the metal organic framework, Uio-66 has excellent adsorption to dyes. It combined with cellulose hydrogel can improve the adsorption performance of the composite hydrogel. Uio-66 can not only optimize the adsorption performance of cellulose hydrogels, but also improve the adsorption rate of composite hydrogels. By changing the amount of Uio-66, we studied the adsorption of methylene blue by composite hydrogel under different initial concentration, temperature, and pH. At room temperature, when the adding amount of Uio-66 was 10% of the mass of cellulose, the composite hydrogel had the best adsorption performance. The adsorption rate was significantly improved, and the maximum adsorption amount was 764.95 mg g−1, which is much better than the cellulose hydrogel without Uio-66, and the time to reach adsorption equilibrium was also significantly shortened.
