Interactions of Aqueous Ag+ with Fulvic Acids: Mechanisms of Silver Nanoparticle Formation and Investigation of Stability
Original language description
This study investigated the possible natural formation of silver nanoparticles (AgNPs) in Ag+-fulvic acid (FA) solutions under various environmentally relevant conditions (temperature, pH, and UV light). Increase in temperature (24-90 °C) and pH (6.1-9.0) of Ag+-Suwannee River fulvic acid (SRFA) solutions accelerated the appearance of the characteristic surface plasmon resonance (SPR) of AgNPs. The rate of AgNP formation via reduction of Ag+ in the presence of different FAs (SRFA, Pahokee Peat fulvic acid, PPFA, Nordic lake fulvic acid, NLFA) and Suwannee River humic acid (SRHA) followed the order NLFA } SRHA } PPFA } SRFA. This order was found to be related to the free radical content of the acids, which was consistent with the proposed mechanism. Thesame order of AgNP growth was seen upon UV light illumination of Ag+-FA and Ag+-HA mixtures in moderately hard reconstituted water (MHRW). Stability studies of AgNPs, formed from the interactions of Ag+-SRFA, over a period of several mon
