Abstract

The widespread use of industrial dyes poses significant environmental and health risks, necessitating the development of efficient removal methods. This study synthesized series of UIO-66 type MOFs, using the solvothermal method and applied them to investigate selective dye adsorption performance. Based on the adsorption results, UIO-66-COOH demonstrated the highest adsorption capacity for Congo Red (CR), reaching 815.0mg/g. This capacity is significantly greater compared to that of UIO-66, which was 237.5mg/g. Isotherm analysis revealed that the uptake of CR by UIO-66-COOH adhered to the Langmuir isotherm, indicating a spontaneous and exothermic reaction. The addition of functional groups markedly improved the performance of UIO-66.
