A Synergistic Complexation‐Encapsulation Paradigm Enables Unprecedented Radioactive Remediation

A novel HDEHP‐APG eutectic mixture‐based detergent is developed that achieves highly efficient decontamination of Am through a synergistic complexation‐encapsulation mechanism. Remarkably, such a detergent effectively removes radionuclides across a wide range of oxidation states (+I to +VII), demonstrating exceptional versatility. These results highlight its significant potential for practical radioactive remediation applications. Abstract 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.
