Nanoarchitectonics of bridged palladium-polyelectrolyte colloidal complexes via reversible coordination-driven assembly and disassembly for closed-loop recovery.
Palladium (Pd) is a critical element in modern technologies, yet it faces supply risks and is often lost in industrial wastewater. In this study, a cystamine-modified polyacrylic acid (Cyst-PAA) was developed for rapid and targeted Pd recovery via S/N cooperative coordination. Binding of Pd(II) through amide N, amine N...
