The plasma reactor, made of a porous hollow ceramic tube, was placed underwater and was able to disperse plasmatic gas containing various reactive species into aqueous dye solution as small bubbles through the micropores of the tube. The hydrophobic coating on the surface of the ceramic tube effectively prevented the water from permeating through it. This wastewater treatment system was able immediately to transfer plasmatic gas to aqueous solution across the porous ceramic tube and provide a large gas–liquid interfacial area, allowing efficient dye treatment. So as to simulate real dyeing wastewater, an aqueous solution comprising two different azo dyes was used. The effect of discharge power, treatment time, and flow rate of oxygen used for the creation of plasma was examined. The results suggest that this system may be useful for the treatment of organic wastewater.

Plasma-photocatalytic degradation of dyeing wastewater : comparison of titanium oxide, zinc oxide, and graphene oxide / Doo Il Jang in COLORATION TECHNOLOGY, Vol. 130, N° 2 (04/2014)

Langues : Anglais (eng) Catégories : Catalyseurs métalliques Colorants -- Détérioration Colorants acides Eaux usées -- Epuration Oxyde de graphène Oxyde de titane Oxyde de zinc Photocatalyse Plasmas (gaz ionisés) Index. décimale : 667.3 Teinture et impression des tissus Résumé : Non-thermal plasma combined with photocatalysis is a viable technique for the degradation of organic impurities in wastewater. In this work, a specially devised dielectric barrier discharge plasma reactor system coupled with photocatalysis was applied to the degradation of CI Acid Red 4 which is commonly used as a textile dye. Dye degradation in the combined system was evaluated with three different photocatalysts: titanium oxide, zinc oxide, and graphene oxide. The photocatalysts were characterised by X-ray diffraction, particle size analysis, and Brunauer–Emmett–Teller specific surface area. It was found that the combination of photocatalysis with plasma substantially improved dye degradation by comparison with plasma alone. To identify which photocatalyst exhibited the best performance, the influence of photocatalysis alone on dye degradation was separately determined using an ultraviolet lamp, which showed that graphene oxide, which has a broad band gap, degraded the dye most effectively.
