“…Since the boiling point of 4-aminobenzenesulfonic acid exceeded the temperature limit of the GC-MS, only N,N-dimethyl-p-phenylenediamine was detected in the GC chromatogram. From the MS analysis, the main fragmentation ions (m/z) were 136, 121, 105, 93, 77, 60, 40 and 18 which were comparable with other researchers in the N,N-dimethyl p-phenylenediamine determination (Parshetti et al, 2010;Cai et al, 2012;Chen et al, 2008).…”

“…Or DMPD may remove one or two methyl groups to yield 1, 4-Benzenediamine, N-methyl-, and PPD at the same time, and the 1, 4-Benzenediamine, N-methyl-may be further degraded to yield PPD. Compared to other researches that study the anaerobic decolorization of MO, the decolorization products were only DMPD and 4-ABS (Cai et al, 2012;Chen et al, 2008;Murali et al, 2013), the other two compounds haven't been reported before. This may because of the anode layer of this study was filled with GAC while the anode of the researches mentioned before were made of carbon paper, carbon fibre or carbon felt, and the anode chamber of these researches were filled with liquid.…”

a b s t r a c tMicrobial fuel cell coupled constructed wetland (CW-MFC) was constructed for azo dye decolorization and further degradation. Methyl Orange (MO) was chosen as the model azo dye due to the simple decolorization products. The decolorization products were analyzed qualitatively via GC-MS and the N,NDimethyl-p-phenylenediamine (DMPD) was chosen as one of the MO decolorization products to study the further degradation performance of decolorization products in the CW-MFC. 1,4-Benzenediamine, N-methyl-and p-Phenylenediamine (PPD) was another intermediate product of MO decolorization. Electrical characteristics of CW-MFC were studied to evaluate the interplay between the azo dye degradation and the electricity generation. The MO decolorization rate of open and closed-circuit CW-MFC were 75.59% and 87.60%, respectively, while the DMPD degradation rate in the anode layer of open and closedcircuit CW-MFC were 84.96% and 96.33%, respectively. In the anode layer, suitable anode materials can promote the further degradation of azo dye degradation products, while in the cathode layer, close current promoted the further degradation of the decolorization products.

“…This effect is seen by numerous groups on various dyes [34][35][36][37][38]. At a higher radiation dose, more reactive species are generated in solution, which in turn are available to react with and degrade dye molecules.…”

“…Amongst the many techniques employed in the AOP approach are the UV photolytic technique [9][10][11][12], Fenton process [13][14][15][16][17][18], photo-Fenton process [19][20][21], ozonation process [22], sonolysis [23][24][25], photocatalytic approach [26][27][28][29][30], biodegradation [31][32][33] and the radiation induced degradation of dyes [34][35][36][37]. Furthermore, many workers have coupled the various AOP techniques to obtain significant improvement in their results [38][39][40][41][42][43]. The present paper is a review of published studies on high energy radiation (␣, ␤ and ␥) induced degradation/decoloration of dye solutions reported during the period of 2000-2008.…”
