Cu-BTC-SiO2材料的制备及其对亚甲基蓝的吸附性能
Preparation of Cu-BTC-SiO2 and its adsorption properties for methylene blue
摘要
Abstract
Cu-BTC-SiO2 was prepared by loading Cu-BTC into the mesoporous silica using in-si-tu synthesis method .The effects of Cu-BTC-SiO2 on the adsorption of methylene blue at differ-ent temperatures ,different methylene blue concentrations and different pH values were stud-ied .At the same time ,the adsorption kinetics and adsorption thermodynamics data were ana-lyzed .The results show that the adsorption of methylene blue on the sample is in accordance with Langmuir adsorption isotherm model and quasi-first order kinetic model .The optimum re-action temperature is 25 ℃ ,the dye concentration 5 mg/L ,and the optimum pH value 5 .The thermodynamic study finds that the adsorption behavior of methylene blue on Cu-BTC-SiO2 is a spontaneous and exothermic process at the temperature between 25 ～ 45 ℃ .关键词
