The significance of platinum in the environment
Brestovská, Marta ; Holubová, Zuzana (referee) ; Sommer, Lumír (advisor)
This bachelor thesis deals with monitoring of individual platinum compounds in the environment (water, soil, air) and is also reviewing methods used for their analysis. The no less important determination of platinum in tissues and body fluids, when the platinum is used in form of a cisplatin as an anticancer drug, is also mentioned. Afterwards the anticancer drug itself or its derivatives and metabolites on the base of platinum complexes in clinical sample (urine, plasma) are determined. Mainly the ICP-AES, ICP-MS, ETA-AAS, HPLC methods are highlighted from the methods used for the determination of Pt. The on-line connection between some of these methods such as ICP-MS with HPLC or ICP-AES with HPLC seems to be useful. The spectrofotometric methods using organic and inorganic agents can also be used for the determination of platinum. These methods are mentioned here rather marginally, just for completeness. In terms of practical use they are difficultly reproducible and not very sensitive. The hydrolysis of platinum metals to form insoluble hydrated oxides makes also the determination difficult.

Determination of tensides in waters by separation methods
Brestovská, Marta ; Řezáčová, Veronika (referee) ; Čáslavský, Josef (advisor)
Surfactants are synthetically made surface-active agents contained in washing and cleaning products. They decrease the surface tension and remove dirt. Surfactants can be divided into three basic classes: anionic, cationic and non-ionic. Thanks to the massive use they penetrate into waste water and can disturb the environment. This diploma thesis deals with the occurrence of surfactants in water and their determination by separation methods, especially LC / MS.
