Demonstrates effective uranium removal in acidic wastewater, suggesting a sustainable solution.
without requiring any external energy input. PA-Fe-PANI shows outstanding uranium adsorption performance over pH 1.0-7.0, reaching a maximum capacity of 130.70 mg/g under the strongly acidic condition at pH 1.0. Tests on actual high-ionic-strength rare-earth tailings wastewater with complicated coexisting ions confirm the composite removes 96.8% uranium. This study develops an energy-neutral, scalable, and chemically stable approach to effectively immobilize uranium in strongly acidic complex industrial wastewater.
