Abstract Extensively used bisphenol A (BPA) in industry aggravates the pollution of water environment. Thus, we are committed to developing an efficient adsorbent to remove BPA, exploring the adsorption performance and mechanism. Here, a novel nitrogen-containing covalent organic framework, named PyTTA-Dva-COF as an effective adsorbent for removing BPA from aqueous solutions was prepared by a simple solvent-thermal method. PyTTA-Dva-COF exhibited uniform nanofibrous structure, abundant and robust C=N functional groups, as well as high chemical stability. The saturated adsorption capacity is 285 mg/g, and the adsorption process conforms to Langmuir isotherm model. The kinetic data conforms to the pseudo-second-order kinetic model, and the thermodynamic parameters, ∆G°
