Extraction of silver from ag2s
WebSulfidation of silver nanoparticles (AgNPs) to generate silver sulfide nanoparticles (Ag 2 S-NPs) significantly influences their fate and toxicity in natural environments. However, the correlational research in this field was limited by the lack of methods for speciation analysis of Ag 2 S-NPs. To address this challenge, a novel protocol for the selective Ag 2 S-NP …
