Abstract: Cu-BTC/GO metal-organic framework composite was prepared by a simple chemical method.The absorption effect of Cu-BTC/GO for methylene blue in aqueous solution was investigated.Cu-BTC/GO was characterized by scanning electron microscope (SEM),transmission electron microscopy (TEM),FT-IR spectroscopy (FT-IR),X-ray powder diffraction (XRD),thermogravimetric analysis (TG) and BET surface area.The effect of temperature,pH and the initial concentration of methylene blue were investigated.The results showed that when the pH of methylene blue solution was 7,125mg/L Cu-BTC/GO had excellent adsorption abilities in the 10mg/L methylene blue solution at 30℃.The adsorption isotherms followed Langmuir equation,and the dynamic data fitted pseudo-second order kinetic model well.When the pH of methylene blue solution was 7,the maximum adsorption capacity of Cu-BTC/GO was 480.77mg/g at 30℃.
