Abstract
- A novel ratiometric electrochemiluminescence (ECL) indicator has been constructed for ultratrace As(iii) detection based on the synergistic quenching of ECL emission of Au–g-C3N4 NSs using As(iii) and Ru(bpy)32+, meanwhile generating a new ECL signal of Ru(bpy)32+ with an increased intensity. Due to the dual quenching effect of As(iii) and Ru(bpy)32+ coupled with the generation of the second ECL signal of Ru(bpy)32+, the sensitivity and selectivity for detecting As(iii) are vastly enhanced.
