2019/2020.

Attendance requirements:

302A1

ECTS:

10

Study level:

basic academic studies

Study program:

Environmental Chemistry: 4. year, winter semester, compulsory course

Teacher:

Konstantin B. Ilijeviæ, Ph.D.
assistant professor, Faculty of Chemistry, Studentski trg 12-16, Beograd

Assistant:

Jovana P. Roganoviæ, Ph.D.
research associate, Faculty of Chemistry, Studentski trg 12-16, Beograd

Hours of instruction:

Weekly: four hours of lectures + six hours of labwork (4+0+6)

Goals:

The main goal of the course Chemistry of Water and Waste Waters is to help undergraduate students acquire fundamental knowledge of the properties and behavior of water and of organic and inorganic pollutants which can be found in it. Students also learn how these pollutants enter the water and how they behave in it. Wastewater purification processes, water sampling and determination of the parameters of water quality are of particular significance since they are a part of standard procedures which are used everywhere in the world.

Outcome:

Students can use standard procedures, determine and assess the quality of water. These skills are important for working in laboratories, industry, inspection services and institutes. This course provides students with the background knowledge which is essential in case they later decide to broaden and increase their knowledge in the field of water in the environment.

Teaching methods:

Lectures and experimental work.

Extracurricular activities:

Collecting literature, preparing for laboratory classes, studying for the progress tests and the exam.
