AB  - Nicotine degradation efficiency in water solutions was studied using a water falling film dielectric barrier discharge (DBD) reactor. Two different treatments were applied: direct treatment, the recirculation of the solution through a DBD reactor, and indirect treatment, the bubbling of the gas from the DBD through the porous filter into the solution. In a separate experiment, samples spiked with nicotine in double distilled water (ddH(2)O) and tap water were studied and compared after both treatments. Furthermore, the effects of the homogeneous catalysts, namely, Fe2+ and H2O2, were tested in the direct treatment. Nicotine degradation efficiency was determined using high-performance liquid chromatography. A degradation efficiency of 90% was achieved after the direct treatment catalyzed with Fe2+. In order to analyze the biodegradability, mineralization level, and toxicity of the obtained solutions, after all degradation procedures the values of the following parameters were determined: total organic carbon, chemical oxygen demand, biochemical oxygen demand, and the Artemia salina toxicity test. The results showed that an increase in biodegradability was obtained, after all treatments. A partial nicotine mineralization was achieved and the mortality of the A. salina organism decreased in the treated samples, all of which indicating the effective removal of nicotine and the creation of less toxic solutions. Nicotine degradation products were identified using ultrahigh-performance liquid chromatography coupled with a linear ion trap Orbitrap hybrid mass spectrometer and a simple mechanism for oxidative degradation of nicotine in non-thermal plasma systems is proposed.

AB  - The formation of hydroxyl radical and long-living chemical species (H2O2, O-3, NO3- and NO2-) generated in the liquid phase of a water falling film dielectric barrier discharge in dependence on the gas atmosphere (air, nitrogen, oxygen, argon and helium) was studied. The chemical molecular probe dimethyl sulfoxide was employed for quantification of. OH, and the influence of hydroxyl radical scavenging on formation of reactive oxygen and nitrogen species was investigated. In addition to liquid analysis, plasma diagnostics was applied to indicate possible reaction pathways of plasma-liquid interaction. The highest. OH production rate of 1.19 x 10 (5) mol l (1) s (1) was found when water was treated in oxygen, with a yield of 2.75 x 10(-2) molecules of. OH per 100 eV. Formation of hydrogen peroxide in air, nitrogen and argon discharges is determined by recombination reaction of hydroxyl radicals, reaching the highest yield of about 0.7 g kWh(-1) when distilled water was treated in argon discharge. Ozone formation was dominant in oxygen and air discharges. Strong acidification along with formation of reactive nitrogen species was detected in water treated in air and nitrogen discharges.

AB  - In this paper we present plasma-based degradation of nicotine in water solutions. Water falling film dielectric barrier discharge (DBD) was used as plasma source operating in air at atmospheric pressure. Solutions containing 50 ppm and 300 ppm of nicotine in distilled or tape water were treated directly and indirectly by plasma. Influence of homogeneous catalysts Fe2+ and H2O2 was also tested. Artemia Salina organisms were used for toxicity tests of treated solutions. Degradation efficiency was the highest in direct plasma treatment of nicotine with Fe2+ as a catalyst and in this case the toxicity test showed the lowest mortality.

AB  - Pharmaceutical compounds have been detected frequently in surface and ground water. Advanced Oxidation Processes (AOPs) were reported as very efficient for removal of various organic compounds. Nevertheless, due to incomplete degradation, toxic intermediates can induce more severe effects than the parent compound. Therefore, toxicity studies are necessary for the evaluation of possible uses of AOPs. In this study the effectiveness and capacity for environmental application of three different AOPs were estimated. They were applied and evaluated for removal of ibuprofen from water solutions. Therefore, two treatments were performed in a non-thermal plasma reactor with dielectric barrier discharge with and without a homogenous catalyst (Fe2+). The third treatment was the Fenton reaction. The degradation rate of ibuprofen was measured by HPLC-DAD and the main degradation products were identified using LC-MS TOF. Twelve degradation products were identified, and there were differences according to the various treatments applied. Toxicity effects were determined with two bioassays: Vibrio fischeri and Artemia salina. The efficiency of AOPs was demonstrated for all treatments, where after 15 min degradation percentage was over 80% accompanied by opening of the aromatic ring. In the treatment with homogenous catalyst degradation reached 99%. V. fischeri toxicity test has shown greater sensitivity to ibuprofen solution after the Fenton treatment in comparison to A. salina.

AB  - In this study the effect of different homogenous catalysts and their dosage on mesotrione degradation in water falling film dielectric barrier discharge (DBD) reactor was investigated. Four catalytic systems Mn2+ /DBD, Co2+/DBD, Fe2+/DBD and H2O2/DBD were examined. In order to find optimal conditions various concentrations of catalysts and specific energy density (SED) values were tested in each system. Mesotrione degradation efficiency was determined by HPLC-DAD and mineralization efficiency by TOC value. Degradation products were identified by UHPLC-Orbitrap-MS and compared after finding out the optimal concentration for each catalytic system. All studied catalytic systems have proved to be successful in improving mesotrione removal, but the highest improvement in degradation efficiency was obtained with catalytic system 5 ppm Fe2+/DBD (by 50% for SED 124 kJ/L) and 10 mM H2O2/DBD for improving mineralization efficiency (by 45% for SED 310 kJ/L). Nine degradation products were identified in catalytic DBD treatments. Main degradation products were: glutaric acid, 2-nitro-4-methylsulfonylbenzaldehyde and 2-nitro-4-methylsulfonylbenzoic acid. H2O2/DBD gave significantly different degradation products than other catalytic systems. Dominant degradation products in other systems were not identified in system with hydrogen peroxide, which supported the fact that the highest mineralization efficiency was achieved with peroxide catalytic system. Global toxicity of samples after degradation in each system was determined using Artemia sauna and they could be considered as "non toxic". (c) 2014 Elsevier B.V. All rights reserved.
