Abstract
At pH 1. Additionally, even in the presence of other coexisting ions at concentrations 100 times higher than Pd(ii), the adsorption efficiency for Pd(ii) remains above 99%. Mechanistic investigations indicate that the adsorption of Pd(ii) by the TpBpy/CS aerogels primarily occurs through the coordination between pyridine N and Pd(ii), as well as the electrostatic interaction between protonated amino groups and Pd(ii). Moreover, the TpBpy/CS aerogel demonstrates exceptional reusability, maintaining an adsorption efficiency for Pd(ii) above 99% after nine adsorption-desorption cycles. Overall, the TpBpy/CS aerogel is a promising monolithic adsorbent for the efficient recovery of Pd(ii) from acidic industrial…
