The utilization of waste from electrical and electronical equipments
Babuš, Ondřej ; Mašek, Ivan (referee) ; Kizlink, Juraj (advisor)
This work deals with processing electric and electronic devices, which are marked as WEEE. It contains legislative frame of processing electric and electronic devices. Then it describes basic technology of processing electrowaste. The separative processes during the recyclation of WEEE are highlighted because of the electrowaste material complexity. There is also the possibilty of using material obtained from WEEE to prepare chemicals for the wood and other material protection which is mentioned in the final part of thesis.

Personal care products as environmental contaminants
Babuš, Ondřej ; Stoupalová, Michaela (referee) ; Vávrová, Milada (advisor)
Synthetic musk compounds were first prepared artificially in the late 19th century. They have been used to perfume cosmetics, detergents and personal care products. The attention of many researchers has been focused on it recently, due to its high penetration into the nature which is a logical consequence of its great use. The main goal of this thesis is to determine the effect of the ultrafiltration on the concentration reduction of substances mentioned above in the industrial waste waters produced by the cosmetic company. Analytes from the sample were extracted using solid phase microextraction (SPME) and on gas chromatography analysis with mass spectroscopy (GC / MS) has been performed. The whole method was optimized and evaluated. Determination of the average efficiency of the ultrafiltration was made based on data obtained before and after ultrafiltration. Such efficiency determines the suitability of use of this method for removal of synthetic musk compounds from waste waters.
