Abstract
In this project, a novel promising electrochemiluminescence probe based on ternary nanocomposite as CuS/CQDs/g-C3N4NS was demonstrated for the accurate monitoring of diazinon as a popular organophosphate pesticide. This nanocomposite as a promoted luminophore was synthesized by a simple microwave method. Carbon quantum dots and copper sulfide nanostructures displayed a good cooperative effect on the signal improvement. Also, boron nitride quantum dots were introduced as a new and effective co-reactant in the negative potential window for a carbon-based electrochemiluminescence system for the first time. The ultra-sensitive electrochemiluminescence platform was truly used for the analysis of diazinon. The broad linear dynamic range and low limit of detection were obtained from 1.0 × 10−15 to 5.0 × 10−9 M and 2.2 × 10−16 M, respectively. Owing to superior proficiency in accurate diazinon analysis, the developed sensor was used as a new applicable probe for quantitative analysis of diazinon in real samples.
