Modeling the Primary Size Effects of Citrate-Coated Silver Nanoparticles on Their Ion Release Kinetics
Abstract
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) were studied by dispersing them in quarter-strength Hoagland medium at two initial concentrations (300 and 600 μg/L). Ag(+) release rates were found to depend on primary particle size and concentration, when other environmental factors (e.g., dissolved oxygen and protons) were kept constant. A kinetic model was developed to describe the Ag(+) release based on the hard sphere theory using the Arrhenius equation. The model fitted the experimental data well with correlation coefficients of 0.97-0.99, and the model usefully interpreted the dependence of ion release kinetics on the primary particle size and concentration. Moreover, the effects of environmental factors (e.g., dissolved oxygen, pH, temperature, and salinity) potentially can be interpreted as well. This model provides fundamental insight into the ion release kinetics of AgNPs in aqueous environments, allowing us to better understand and predict the nanotoxicity of AgNPs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
