Abstract: In this paper, the uniform morphological Ag nanoparticles (Ag NPs) were prepared with ascorbic acid as the reducing agent and citrate as the stabilizer. The surface of Ag NPs modified by crystal violet (CV) and potassium iodide (KI) is used as the aggregation agent to obtain CV modified Ag NPs (CV-Ag NPs) probes for detecting mercury ions.The mercury ions can be reduced to mercury molecules by citrate, and then deposited them on the surface of Ag NPs, leading to the separation of CV molecules from the surface … Show more
