An integrated experimental-modeling approach to study the acid leaching behavior of lead from sub-micrometer lead silicate glass particles

- Generation of particles by laser ablation of lead silicate glass.
- Collection of particles on filters and continuous acid leaching and ICP-MS monitoring.
- Fitting of the lead leaching profile to a mathematical intraparticle diffusion model.
- Extraction of individual leaching profiles for selected mono-dispersed size fractions.
- Leaching kinetics is based on ion-exchange and correlated with particle size.
