TpBD-3COOH COF的制备及对废水中罗丹明B吸附性能研究
Preparation of TpBD-3COOH COF and the Adsorption of Rhodamine B in Wastewater
摘要
Abstract
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.关键词
