Course content
- Introduction, history of surfactants. - Explanation of basic terms, surface phenomena. - Surface properties of solutions, soaps. - Heterogeneous systems: foams, emulsions, suspensions. - Physical properties of surfactants - solubility, adsorption, micelles. - Technical properties of surfactants - solubilisation, wettability, emulsification, detergency. - Anionic surfactants - with carboxyl group (soaps). - Anionic surfactants - sulphates. - Anionice surfactants - sulphonates. - Cationic surfactants. - Amphoteric surfactants. - Non-ionic surfactants. - Examples of surfactants and their applications. - Surfactants and environment.

Learning activities and teaching methods
Monologic (Exposition, lecture, briefing), Simple experiments
  • Home preparation for classes - 20 hours per semester
Learning outcomes
The subject is aimed at gaining knowledge about surfactants, especially their structure, physical and technical properties, preparation techniques and practical industrial applications. Students will acquire knowledge about the main classification of tensides and principles of their action.
The student has knowledge about basic surface phenomena and surface properties of solutions. He/she is able to estimate the properties and potential applications of the given surfactant on the basis of its general structure.
Prerequisites
Knowledge of Colloid and surface chemistry, Physical chemistry.

Assessment methods and criteria
Grade (Using a grade system), Oral examination, Written examination, Analysis of works made by the student (Technical products)

The way of course termination - exam. Attendance: compulsory attendance at laboratory practices (100%). Course credit: elaboration of required amount of laboratory experimental reports with evaluation, discussion and conclusion. Examination: knowledge of the curriculum content, written exam, possibility of oral examination. The result of a subject examination is expressed on a six-point scale: A "výborně" (i.e. "excellent"), B "velmi dobře" (i.e. "very good"), C "dobře" (i.e. "good"), D "uspokojivě" (i.e. "satisfactory"), E "dostatečně" (i.e. "sufficient"), F "nedostatečně" (i.e. "fail").
