Electrochemiluminescence Sensor Based on TPEA-RuMOF: For Highly Selective and Sensitive Detection of Copper Ions

Graphical In this study, we present the novel combination of AE-TPEA with RuMOF to construct an electrochemiluminescence (ECL) sensor using a TPEA-RuMOF composite material specifically for copper ions (Cu 2+ ) detection. Using K 2 S 2 O 8 as a co-reactant, we explored the ECL behavior of the TPEA-RuMOF modified electrode, enabling the quantitative detection of Cu 2+ . Remarkably, this sensor exhibited a wide linear range from 1×10 −5 to 1×10 −9 M (R 2 =0.998) and boasted a detection limit as low as 0.41 nM, which is considerably below the EPA (Environmental Protection Agency) permissible copper ion concentration in drinking water of <1.3 mg/L. our synthesized probe offers enhanced stability and selectivity in copper ion detection. This indicates its considerable potential for high-performance copper ion detectors. We further validated the analytical applicability of this sensor using river water samples.
