Syllabus

1. A survey of modern analytical separation techniques.

2. Theory of separations based on the concepts of differential migration of the analytes.

3. Physico-chemical principles of the underlying processes and interactions, i.e., transport phenomena (diffusion, convection), solubility (precipitation, coprecipitation, dissolution), adsorption, ion exchange, size exclusion, biological recognition.

4. Single step separation methods - precipitation and co-precipitation, electrodeposition, liquid-liquid extraction.
