AB  - Purpose Every advanced oxidation process (AOP) has its limitations in water purification. Novel designs with simultaneous application of different AOPs can offer better solutions for cleaner water. Methods We have comparatively studied two advanced oxidation processes (AOPs) on decolourisation of Reactive Orange 16 (RO 16) azo dye pollutant from water: gas plasma treatment by low power atmospheric pressure plasma using novel plasma needle configuration, and semiconductor heterogeneous photocatalysis using titanium dioxide (TiO2) nanopowders. Additionally, simultaneous application of two advanced oxidation processes on azo dye decolourisation was studied. Results It was found that plasma treatment is very efficient system for the dye removal even for low flow rates (1 slm) of the Ar as feed gas. The presence of 10% of O-2 in Ar flow intensified dye oxidation process and shortened required time for total decolourisation. When plasma and catalyst were simultaneously applied, TiO2 was activated with a few Watts plasma source as well as 300 W UV lamp source. The synergic effect of two AOPs was more pronounced for higher feed gas flow rates, resulting in improved decolourisation efficiency. Conclusion Plasma needle can efficiently remove Reactive Orange 16 azo dye from water with a power consumption of only few Watts. With the addition of TiO2 the removal efficiency is significantly improved. [GRAPHICS] .

AB  - Titanium dioxide (TiO2) nanopowders were produced by sol-gel technique from tetrabutyl titanate as a precursor by varying some parameters of the sol-gel synthesis, such as temperature (500 and 550 degrees C) and the duration of calcination (1.5, 2 and 2.5 h). X-ray powder diffraction (XRPD) results have shown that all synthesized nanopowders were dominantly in the anatase phase, with the presence of a small amount of rutile in samples calcined at 550 degrees C. According to the results obtained by the Williamson-Hall method, the anatase crystallite size was increased with the duration of the calcination (from 24 to 29 nm in samples calcined at lower temperature, and from 30 to 35 nm in samples calcined at higher temperature). The analysis of the shift and line-width of the most intensive anatase Eg Raman mode confirmed the XRPD results. The analysis of pore structure from nitrogen sorption experimental data described all samples as mesoporous, with mean pore diameters in the range of 5-8 nm. Nanopowder properties have been related to the photocatalytic activity, tested in degradation of the textile dye (C.I. Reactive Orange 16), car-bofuran ray scattering.

AB  - The effects of common precursors used in the synthesis of CeO2 nanopowders were investigated, and the structural and spectral properties of the resulting products were compared. Two cerium (III) salts, i.e., Ce(NO3)(3)center dot 6H(2)O and CeCl3 center dot 7H(2)O, and two cerium (IV) salts, i.e., Ce (SO4)(2)center dot 4H(2)O and (NH4)(2)Ce(NO3)(6) were applied. The proposed procedures for the CeO2 preparations were realizdd using the same hydrothermal treatment conditions. The products were characterized using X-ray powder diffraction (XRD) and thermogravimetric (TG) analysis, and the morphology was determined using scanning (SEM) and transmission electron microscopy (TEM). The spectral properties of the obtained nanopowders were characterized by FT-IR, Raman scattering and UV-vis spectroscopy. The results revealed the influence of the precursors on the crystallinity, crystallite size, band gap energy, morphology and purity of the synthesized samples.

A precursor was titanium tetrachloride and concentrations of dopants were 0.5 and 1.0 mol%. Procedures of both methods were the same, up to the last part of synthesis (the transformation from the mother liquor to oxide nanopowders), in order to find the influence of applied methods on the properties of nanopowders. XRD results have shown that all synthesized nanopowders were in the anatase phase. It was seen from DSC measurements that anatase to rutile phase transition took place at a higher temperature with a higher concentration of dopant (La3+). The samples obtained by the sol gel method had a higher temperature of phase transition than related samples obtained by the hydrothermal method. Nanopowder properties have been related to the photocatalytic activity, tested in degradation of the pharmaceutical alprazolam. (C) 2014 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - In this work, zinc oxide powders were obtained by two different techniques: hydro- and solvothermal synthesis starting from Zn(NO3)(2) and Zn(CH3COO)(2), respectively. The influence of synthetic procedure on the structural, microstructural, thermal and photocatalytic properties of the prepared ZnO powders was investigated. Both ZnO samples were further annealed under moderate conditions (300 degrees C) to avoid grain growth and to remove traces of impurities. In all four cases, single-phase hexagonal ZnO was confirmed by X-ray powder diffraction. The morphologies of prepared ZnO powders were different and they varied from rounded nanograins to microrods. All prepared samples showed higher photocatalytic efficiency in the degradation of the textile azo dye Reactive Orange 16 (RO16) than commercial ZnO. In addition, the non-annealed samples had better photocatalytic properties than the commercial Degussa P25 TiO2 powder.

abstract = "In this work, zinc oxide powders were obtained by two different techniques: hydro- and solvothermal synthesis starting from Zn(NO3)(2) and Zn(CH3COO)(2), respectively. The influence of synthetic procedure on the structural, microstructural, thermal and photocatalytic properties of the prepared ZnO powders was investigated. Both ZnO samples were further annealed under moderate conditions (300 degrees C) to avoid grain growth and to remove traces of impurities. In all four cases, single-phase hexagonal ZnO was confirmed by X-ray powder diffraction. The morphologies of prepared ZnO powders were different and they varied from rounded nanograins to microrods. All prepared samples showed higher photocatalytic efficiency in the degradation of the textile azo dye Reactive Orange 16 (RO16) than commercial ZnO. In addition, the non-annealed samples had better photocatalytic properties than the commercial Degussa P25 TiO2 powder.",

AB  - Ultrafine CeO2-delta nanopowder, prepared by a simple and cost-effective self-propagating room temperature synthesis method (SPRT), showed high adsorption capability for removal of different azo dyes. Batch type of adsorption experiments with fixed initial pH value were conducted for the removal of Reactive Orange 16 (RO16), Methyl Orange (MO), and Mordant Blue 9 (MB9). The equilibrium adsorption data were evaluated using Freundlich and Langmuir isotherm models. The Langmuir model slightly better describes isotherm data for RO16 and MO, whereas the Freundlich model was found to best fit the isotherm data for MB9 over the whole concentration range. The maximum adsorption capacities, determined from isotherm data for MO, MB9, and RO16 were 113, 101, and 91 mg g(1) respectively. The adsorption process follows the pseudo-second-order kinetic model indicating the coexistence of chemisorption and physisorption. The mechanism of azo dye adsorption is also discussed.
