Colloidal State and Surface Chemistry

Colloids and surface chemistry at PGT depth: classification of colloids, preparation and purification (dialysis, electrodialysis, ultrafiltration), Tyndall effect, Brownian motion, zeta potential and coagulation (Hardy–Schulze rule), gold number, emulsions and gels; adsorption isotherms (Freundlich, Langmuir, BET), physisorption vs chemisorption, and catalysis.
