摘要

Uranium plays a crucial role in the nuclear energy sector, yet its radiological and chemical characteristics can pose environmental and public health hazards. This study introduces a novel bimetallic system based on cation-cation interactions, involving the binding of europium ions (Eu3+) to uranyl ions (UO22+) via phosphate bridges. The method exhibits excellent linearity in the uranyl ion concentration range of 10–90 nM, with a detection limit as low as 10 nM. The system has been successfully applied to detect UO22+ in actual water samples and for fluorescence imaging of UO22+ in cells. These findings highlight the potential of Eu-P as a promising material for sensing UO22+, offering significant contributions to environmental monitoring and public health protection.
