Determination of tensides in waste and waste waters
Sigetová, Martina ; Repková, Martina (referee) ; Vávrová, Milada (advisor)
Surfactants belong to the surface active agents with the ability to reduce surface tension, which is used mainly in detergents and cleaners. The diploma thesis is focused on the determination of surfactants in waste and waste waters. The theoretical part describes the basic properties of surfactants, their distribution, valid legislation in the EU and SR in the field of working with these materials and a variety of analytical methods for the determination of these substances. The conclusion of the thesis is to evaluate the results of measuring the concentration of anionic surfactants, which were determined in samples of waste water and sludge.

PCBs as significant dangerous chemical waste
Sigetová, Martina ; Vávrová, Milada (referee) ; Kizlink, Juraj (advisor)
The bachelor thesis is focused on the problems of polychlorinated biphenyls. In the introduction there are written the basic physical and chemical properties, production and PCB influence onto the constituent elements of the environment. In the next part the thesis occupies the analyse of present state of PCB and valid legislation in SK in the field of working with this material.
