| Summary: | HKUST-1 crystals with excellent properties are grown in situ on low-cost and high-stability diatomite-based porous ceramic (DBPC) by the non-uniform nucleation growth method.The successful preparation of the composite DBPC@HKUST-1 is verified by XRD,FTIR,and SEM characterization.At the same time,the adsorption performance of DBPC@HKUST-1 for methylene blue (MB) is studied,and the adsorption kinetics,adsorption isotherm,adsorption thermodynamics and the influence of pH are analyzed.The results show that the adsorption behavior is consistent with the quasi-second-order kinetic model and Freundlich isothermal model.The maximum adsorption capacity of DBPC@HKUST-1 for MB is 378.788 mg/g.The adsorption thermodynamics indicates that the adsorption behavior is a spontaneous exothermic reaction.Therefore,DBPC@HKUST-1,as a cheap green adsorbent,is expected to be the best candidate material for the treatment of organic dye wastewater in the future industry. |
