Cilji in kompetence:

Objectives and competences:

Glavni namen predmeta je razumevanje osnov koloidne in površinske kemije ter predstavitev fizikalno-kemijskih procesov na fazni meji med trdno snovjo in raztopino (površina koloidov – raztopina). Predmet je usmerjen v razumevanje vloge koloidov pri kemijskih in bioloških reakcijah, pri mobilnosti in transportu polutantov v naravnih okoljih in v tehnologiji.

Predmet seznanja študente z osnovami koloidne kemije in njihovo uporabo v okolju in tehnologijah.

It concerns selected topics of fundamental of Colloid and Surface Chemistry. Introduction to physicochemical processes at the solid/liquid (surfaces of colloids – aquatic system) interfaces. The course is devoted towards understanding their role in the chemical and biological reactions, mobility and transport of contaminants in natural environments and engineered aquatic systems.

This course prepares students in the fundamentals of colloid chemistry and their application in the environment and corollary technologies.
