| Zusammenfassung |
| Critical supersaturations for internally mixed particles of adipic
acid, succinic acid and sodium chloride were determined
experimentally for dry particles sizes in the range
40-130nm. Surface tensions of aqueous solutions of the
dicarboxylic acids and sodium chloride corresponding to
concentrations at activation were measured and parameterized as a
function of carbon content. The activation of solid particles as
well as solution droplets were studied and particle phase was
found to be important for the critical supersaturation.
Experimental data were modelled using Köhler theory modified to
account for limited solubility and surface tension lowering. |
