Interfacial assembly of PBAs/ZIF-8 composites for ultrahigh-capacity and selective thallium capture with exceptional alkaline tolerance.
Effective Tl+ elimination under extreme alkaline pH remains challenging, as alkali triggers decomposition of Prussian blue analogs (PBAs), lowering adsorption efficiency and generating secondary pollutants. Furthermore, conventional PBAs nanocrystals (<100 nm) require costly high-speed centrifugation for separation. He...
