Description

The adsorption behavior of congo red from aqueous solution on Cu-BTC/SiO2 was investigated. Cu-BTC/SiO2 with mesoporous structure and large surface area was prepared by loading Cu-BTC into the mesoporous silica using in-situ synthesis method. The X-ray diffraction, scanning electron microscopy, and nitrogen adsorption–desorption analysis were used to characterize the structure and morphology of the prepared materials. The adsorption studies showed that the adsorption isotherm of congo red on Cu-BTC/SiO2 fitted well with Freundlich adsorption model and congo red is easy to be adsorbed by Cu-BTC/SiO2. The thermodynamic study showed that the adsorption behavior of congo red on Cu-BTC/SiO2 is an exothermic process at temperature under investigation. Graphic abstract:
