REZIME
Nikotin je alkaloid koji se nalazi u nekim biljkama, ali je njegov glavni izvor duvan, koji se
koristi za proizvodnju cigareta. Nikotin je takođe sastavni deo nekih farmaceutskih proizvoda i
shodno tome, pored proizvodnje cigareta, lekovi bazirani na nikotinu su još jedan izvor ove
supstance koja može da stigne u industrijske i komunalne otpadne vode. Osnovni cilj ovog rada
je bio ispitivanje efikasnosti degradacije vodenog rastvora nikotina pomodu plazma reaktora koji
radi na principu dielektričnog barijernog pražnjenja (DBD, Dielectric Barrier Discharge). Početne
koncentracije nikotina u rastvorima su bile 50,0 i 300,0 mg/L. Vreme tretmana je bilo 60 min, a
kinetika degradacije je pradena na svakih 10 min pomodu HPLC (HPLC, High Performance Liquid
Chromatography) analitičke tehnike. Tretman rastvora nikotina je izveden direktnim,
katalitičkim i indirektnim postupkom.

SUMMARY
Nicotine is an alkaloid found in some plants, but its major source is tobacco, which is
used for production of cigarettes. Nicotine is also a constituent of some pharmaceutical
products and, therefore, apart from the production of cigarettes, nicotine-based drugs are
another source of this substance that can get to industrial and municipal wastewater. The main
objective of this study was to investigate the degradation effectiveness of nicotine aqueous
solution by plasma reactor that works on the principle of dielectric barrier discharge (DBD,
Dielectric Barrier Discharge). The initial concentrations of nicotine in aqueous solutions were
50.0 and 300.0 mg/L. Treatment time was 60 min, and the degradation kinetics was monitored
every 10 min by HPLC analytical technique (HPLC, High Performance Liquid Chromatography).
Treatment of nicotine solution was performed directly, catalyticly and indirectly.
Key words: nicotine, degradation, Advanced Oxidation Process (AOP), plasma reactor,
