Ion release is an important environmental behavior of silver nanoparticles (AgNPs), and characterization of Ag+ release is critical for understanding the environmental fate, transport, and biological impacts of AgNPs. The ion release kinetics of AgNPs with three primary diameters (20, 40, and 80 nm)...
