XPS study of the NH4-VOx powders
Open Research DataVanadium pentoxide samples were prepared by sol-gel method. The starting solution was prepared by mixing vanadium (V) oxytripropoxide (Aldrich) in an anhydrous ethanol as solvent and acetylacetone. By drying the sol at 323 K for 48 h, it transforms via gel into a xerogel powder. Next, the precursor powder was pressed into the disk-shaped pellets. Samples...

Monitoring of occupational exposure to volatile organohalogen solvents (VOXs) in human urine samples of dry-cleaner workers by TLHS-DAI-GC-ECD procedure
PublicationChlorinated hydrocarbon solvents are often used for dry-cleaning clothes in the laundry industry. The object of this study was to monitor the occupational exposure of dry-clean employees coming into contact with VOXs. 25 workers collected their urine samples before the work shift, after 4 hours of work and after the work shift. The analyses of urine samples and solvents used in dry-cleaning were performed using TLHS-DAI-GC-ECD....

Volatile Organohalogen Compounds Determination with Dispersive Liquid-Liquid Microextraction Applying Solvent Lighter than Water
PublicationBackground: Volatile organohalogen compounds (VOX) are a group of environmental pollutants that risk the quality of drinking water. These compounds are characterized by certain acute and chronic toxicities, possessing mutagenic properties. Because of these potential risks factors that these compounds cause, the maximum allowable concentrations (MACs) have been established by respective organizations. The abundance of VOX, their...

Monitoring of organic pollutants in coastal waters of the Gulf of Gdańsk, Southern Baltic.
PublicationPrzedstawiono zmiany zawartości zanieczyszczeń organicznych (np. VOC, PAH, PCB, chlorofenoli) w wodach Zatoki Gdańskiej na przestrzeni 5-ciu lat. Zawartość VOX i VOC zmieniała się od kilku ngdm-3 do kilkuset ngdm-3, podczas gdy zawartość chlorofenoli fenoksykwasów była na poziomie kilku ngdm-3. W większości próbek nie wykryto PCB.

Wytwarzanie cienkich warstw azotku wanadu metodą termicznego azotowania tlenku wanadu
Publicationw niniejszej pracy opisano metodę wytwarzania cienkich warstw vn - sio2 poprzez termiczne azotowanie powłok vox - sio2. warstwy tlenku wanadu zostały naniesione na szklane podłoża metodą zol - żel. po wysuszeniu nastąpiło wygrzanie warstw w atmosferze amoniaku. wygrzewanie w temperaturze wyższej, od temperatury dysocjacji termiczne amoniaku, mikroporowatych warstw tlenku wanadu spowodowało azotowanie materiału. w konsekwencji procesu...
