A Synergistic Complexation-Encapsulation Paradigm Enables Unprecedented Radioactive Remediation.

The escalating global warming and surging energy demands have accelerated the pursuit of low-carbon, stable, and high-density nuclear energy as a sustainable alternative to conventional fossil fuels. However, nuclear energy deployment inevitably generates radioactive contamination, posing persistent risks to ecosystems and human health. The effective removal of radioactive pollutants remains a critical yet unresolved challenge. In this study, a novel and straightforward eutectic mixture-based detergent is presented to address this issue. Leveraging an innovative synergistic mechanism integrating complexation and encapsulation, rapid and highly efficient decontamination of americium (Am), a potent α-emitter, is achieved. Additionally, this detergent exhibits exceptional versatility, effectively removing radionuclides across a broad spectrum of oxidation states (+I to +VII). These results highlight its significant potential for practical application in radioactive remediation.
