Dissolution of commercial nanoscale silica particles in electrolyte solution: The importance of the solid-solvent-ratio to physical and chemical properties of the solid-liquid interface

摘要

Graphical abstractDisplay OmittedHighlights?The shape of the kinetic dissolution curves of nanoparticles, NPs, depends on the solid to solvent ratio.?The kinetic size effect a solubility maximum in the kinetic dissolution curves of NPs can be observed for different materials.?This phenomenon can be explained by variation of the surface contribution to the Gibbs free energy, G, of the system.?Analysis of G provides size, concentration, and actual solid surface available for dissolution of the NPs at any time of dissolution.?Surface charge, surface potential and solid – liquid interfacial tension as function of the actual size of the NPs can be calculated.展开▼
