Abstract

In this study, a hydrochloric acid-stable 2D covalent organic framework (TpPa-1) was prepared. And its adsorption behaviors in the recovery of palladium (Pd(II)) from hydrochloric acid solution was systematically investigated under the effect of contact time, hydrochloric acid concentration, chloride ions concentration, and adsorption capacity. The adsorbed species on TpPa-1 was clarified as chloridated Pd(II) by X-ray photoelectron spectroscopy.
