To assess the impact of copper ion concentration on the dissolution of PVP-coated AgNPs and the role of the chloride ion, experiments were conducted in both chloride and deionized (DI) water. In an aqueous medium without chloride ions, AgNPs remain stable despite the presence of cupric ions. However, in a chloride medium, their solubility increases in direct proportion to the cupric ion concentration. The dissolution rate of AgNPs was monitored using UV-Vis absorption spectroscopy, leveraging their plasmonic properties. This method allowed us to analyze the dissolution process of PVP-coated AgNPs in sodium chloride solution in the presence of cupric ions. Additionally, using the Bathocuprione method and EDS analysis, the dissolution mechanism of AgNPs into solid silver chloride (AgCl) and cuprous ions within the sodium chloride medium containing cupric ions has been elucidated.
