Palladium (Pd), a rare and precious metal, is highly valued due to its non-renewable nature significant cost. Therefore, recovering palladium from industrial wastewater of great importance but remains challenge. Herein, composite aerogel adsorbent has been developed by linking bipyridine covalent organic framework, termed TpBpy, with chitosan (CS) through robust bonds. The resulting TpBpy/CS employed for the selective separation recovery at low concentrations in real wastewater. Experimental results reveal that maximum adsorption capacity Pd(ii) 274.4 mg g-1 pH 1. Additionally, even presence other coexisting ions 100 times higher than Pd(ii), efficiency above 99%. Mechanistic investigations indicate aerogels primarily occurs coordination between pyridine N as well electrostatic interaction protonated amino groups Pd(ii). Moreover, demonstrates exceptional reusability, maintaining an 99% after nine adsorption-desorption cycles. Overall, promising monolithic efficient acidic selectivity, demonstrating substantial potential practical applications.
