✦ Synopsis

Adsorption of the monovalent cations Cs+ and Na+ from mixed solutions of NaCl and CsCl at the TiO2(anatase)/water interface was studied. Higher adsorption of Cs+ than Na+ was observed from solutions of similar electrolyte concentration. The surface ionization and complexation constants of surface hydroxyl groups were determined using potentiometric titration data. Results for the adsorption of Cs+ and Na+ from mixed electrolyte solutions showed that these ions adsorb at different distances from the metal oxide surface.

## Abstract The electric double layer (EDL) and electroosmotic flows (EOFs) constitute the theoretical foundations of microfluidics. Numerical solution is one of the effective means of analysis in microfluidics. In general, it is difficult to obtain an accurate numerical solution of complex EOFs be
