The degradation of several organic compounds in aqueous solution: methyl yellow (C 14 H 15 N 3 ), methyl red (C 15 H 15 N 3 O 2 ), methyl orange (C 14 H 14 N 3 NaO 3 S), phenol red (C 19 H 14 O 5 S) and methylene blue (C 16 H 18 ClN 3 S), was investigated in a pulsed corona discharge. High voltage pulses of 17 kV amplitude, 24 ns rise time and approximately 200 ns duration (full width at half maximum--FWHM) were applied to an array of six hollow needles. When oxygen was bubbled into the solution through the needle, current pulses of 90 A amplitude were obtained and the average power dissipated in the discharge was 19 W at 100 Hz pulse repetition rate. UV-visible spectra of the aqueous solutions show a significant reduction of the absorbance in the visible range, up to 90%, after plasma treatment, suggesting fragmentation of the compounds. Several aliphatic compounds were identified as oxidation products of methyl yellow, methyl red and methyl orange. For methylene blue and phenol red aromatic reaction products were detected as well.

“…The powerfulness of the hydroxyl radical gives advanced oxidation processes the ability to achieve oxidative destruction of compounds refractory to conventional hydrogen peroxide or ozone oxidation. AOPs have been used successfully for example, destroying pesticides by photochemical degradation (UV/O 3 and UV/H 2 O 2 ) (Andreozzi et al, 2003), photocatalysis (TiO 2 /UV, Fenton and photo-Fenton process) (Legrini et al, 1993;Fallman et al, 1999) (Harrelkas et al, 2008) and also for the destruction of organics in different kind of effluents, such as paper mill wastewaters by photocatalysis (Pérez et al, 2001), landfill leachates by the Fenton process (Lopez et al, 2004;Gotvajn et al, 2009 ), olive mill wastewaters by wet air oxidation (Gomes et al, 2007) etc. Advanced oxidation methods can be split into "cold" and "hot" oxidation.…”

“…Compared with dark Fenton reaction, photo-Fenton process has numerous advantages such as the increase of degradation rate, minimize in sludge generation and the use of solar energy, among others (Malato et al, 2002;De Laat and Le Troung, 2006;Chacón et al, 2006, Orozco et al, 2008. Photo-Fenton process is among the most efficient methods to generate hydroxyl radicals (Bauer et al, 1999). Even higher than other very well studied and widely applied AOPs such as TiO 2 /UV and H 2 O 2 /UV as shown in comparative studies using 4-chlorophenol as model wastewater contaminant (Krutzler and Bauer, 1999).…”

Even higher than other very well studied and widely applied AOPs such as TiO 2 /UV and H 2 O 2 /UV as shown in comparative studies using 4-chlorophenol as model wastewater contaminant (Krutzler and Bauer, 1999). Many parameters, such as initial concentration of ferric salt and hydrogen peroxide, the ratio of [H 2 O 2 ] 0 /[Fe(II)] 0 , pH, light intensity and temperature influence on the efficiency of photo -Fenton process (Bandala et al, 2007;Lee and Yoon, 2004) are determinants in the efficiency.…”
