Abstract
An acid-stable 2D covalent organic framework (COF TpPa-1) was synthesized by a reversible Schiff-base reaction and the following irreversible enol-keto tautomerism. The adsorption behaviors of COF TpPa-1 towards Pd(II) in simulated highlevel liquid waste (HLLW) were investigated under the effect of contact time, the concentration of nitric acid etc. The obtained experimental results supported that the utilization of this type of acid-stable COF in HLLW to recover metal ion was feasible.
