Physical and Colloid Chemistry

Course Description

Study program: Environmental Engineering (V semester -OAS), Geology (III semester -OAS), Mineral Processing (VII semester -OAS), Petroleum Engineering (V semester -OAS)

Name of subject: Physical and Colloid Chemistry

Instructors: Dr Dušica Vučinić

Status: Compulsory

ECTS: 5

Prerequisites: -

Course Objectives: Introduction to the basic laws of physicochemical processes related to the structure and properties of substances, the thermodynamic study of the direction and balance of the process, the process at the boundary of the phase, the coarse dispersed (suspensions and emulsions) and the colloidal systems, the rheology and stability of colloids, coagulation and flocculation, electrochemistry and chemical kinetics some of the methods of physicochemical analysis, in order to predict possible pollution of the environment and its protection and the application of acquired knowledge in certain areas.

Learning Outcomes: By having knowledge in the fields of physical chemistry, a student can: Identify conditions and anticipate the consequences of a physical chemistry process, or, in the end, take protective measures to eliminate harmful consequences, minimize or prevent them, and follow other courses envisaged as compulsory or elective, for which the knowledge required by this subject is required.
