Kinetics of silver nanoparticles formation. Silver ions (Ag+) at 0.93 mM were incubated with particular organic matter (POM) at 143.2 mg C L−1 under simulated sunlight at pH 8.6. The amount of AgNPs and Ag+ in a liquid and b particulate phase. Total amount of c AgNPs and d Ag+ in the heterogeneous system, and the experimental data were fitted using the Finke–Watzky model. Error bars represent the standard deviation of the mean of the triplicates
