Novel carboxyl-functionalized two-dimensional covalent organic frame materials TpBD-3COOH COF was synthesized by a solvothermal method using triacetaldehyde mesitylphenol (Tp), 4, 4-diaminobiphenyl-2, 2-dicarboxylic acid (DBd), and biphenylenediamine (BD) as raw materials, and used for adsorption of Rhodamine B dye wastewater. TpBD-3COOH COF were characterized by XRD, FT-IR and SEM. The results show that the removal of Rhodamine B can reach 95% after 60 min under the conditions of pH=4, TpBD-3COOH COF addition of 8 mg and Rhodamine B mass concentration of 10 mg/L in the wastewater. After five repetitive experiments, the removal rate of Rhodamine B by TpBD-3COOH COF still reaches more than 70%. The adsorption process is consistent with the quasi-second-order kinetic model and the Langmuir adsorption isothermal model.
