Physical chemistry of colloids 0600-S2-ChK-FK

Concept of colloidal state; degree of dispersion; classification of colloids according to the state of matter of continuous and dispersed phases; lyophobic, lyophilic, phase, molecular, association colloids; emulsions, aerosols, foams, powders, suspensions, pastes; surface phenomena: interfacial tension, adsorption (Gibbs equation); structure of colloidal particle; stability of colloids: electric charge, solvation, electrostatic, van der Waals, dispersion interactions; methods of colloid preparation: dispersion, condensation; cleaning colloids: dialysis, electrodialysis, diafiltration; optical properties: Tyndall effect, nephelometry, ultramicroscope; rheological properties: viscosity of Newtonian and Non-Newtonian Fluids; electrokinetic phenomena: electrophoresis, electroosmosis, streaming potential; destruction of colloid systems: coagulation, coalescence, flocculation, sedimentation; colloids in the food industry: hydrocolloids (polysaccharides, proteins), food emulsions (milk, etc.).
Laboratory:
coagulation of sol under the electrolyte influence; turbidimetric determination of critical coagulation concentration; determination of critical micellar concentration; pH dependence of gel swelling; nephelometric determination of sol concentration; foam stability; sedimentation of suspension.
