A 2D covalent organic framework (COF TpPa-1) was synthesized by reversible Schiff-base reaction and the following irreversible enol-keto tautomerism. The adsorption behaviors of COF TpPa-1 towards palladium (Pd(II)) in acid solutions (hydrochloric acid, nitric acid) were investigated under the effect of contact time, concentration of acid etc. The adsorbed species on COF TpPa-1 were further clarified by X-ray photoelectron spectroscopy.
