Abstract

Kinetics of disappearance of seven different disperse dyes were determined in compacted sediments at room temperature. The commercial dyes (in dispersed solid form) were representative of nitroazo, anthraquinone, and quinoline structures that are widely used. Reaction rates were found to be first order over at least two half-lives and were different for the three groups of dyes. Half-lives were on the order of hours, days and months for the nitroazobenzene, aminoanthraquinone, and quinoline dyes, respectively. Stability of the latter is consistent with detection of a quinoline dye in treatment plant sludge and in sediment from a water body receiving treated effluent. The azobenzene dyes are degraded by cleavage of the azo group to give anilines and ring-substituted phenylenediamines from the diazo component of the molecule. Products from the other portion (coupling component) of the molecule are unidentified, as yet, but are expected to be N,N-disubstituted phenylenediamines. Products of the anthraquinone dyes were unidentified, except for the case of a nitrated dye on which the nitro group was reduced.

Degradation characteristic of monoazo, diazo and anthraquinone dye by UV/H{sub 2}O{sub 2} process

Journal Article

In this study, the degradation characteristic of monoazo, diazo and anthraquinone dye by UV/H{sub 2}O{sub 2} process was evaluated based on the trend of color, chemical oxygen demand (COD) and total organic carbon (TOC) removal. Three types of dyes consist of monoazo, diazo and anthraquinone dyes were used to compare the degradation mechanism of the dyes. The UV/H{sub 2}O{sub 2} experiments were conducted in a laboratory scale cylindrical glass reactor operated in semi-batch mode. The UV/Vis characterization of monoazo, diazo and anthraquinone dye indicated that the rapid degradation of the dyes by UV/H{sub 2}O{sub 2} process is meaningful with respectmore »« less

Photolysis of smoke dyes on soils

Journal Article Adams, R; Weber, E; Baughman, G - Environmental Toxicology and Chemistry; (United States)

Photolysis of an azo, a quinophthalone, and several anthraquinone smoke dyes was studied on soil surfaces. Initially, rapid photodegradation of each dye occurred, followed by a period of much slower rate of loss, indicating that the remaining fraction of the dye was photochemically protected. The average mean depths of photolysis ranged from 0.33 to 0.68 mm for outdoor studies and from 0.42 to 0.73 mm for lab studies. The magnitude of the mean depths of photolysis suggests that photo-degradation of the dyes occurs through indirect photochemical processes. Photolysis products for only two of the dyes could be identified. Photolysis ofmore »« less

Degradation of azo dyes by the lignin-degrading fungus Phaerochaete chrysosporium

Journal Article Spadaro, J; Gold, M; Renganathan, V - Applied and Environmental Microbiology; (United States)

Under nitrogen-limiting, secondary metabolic conditions, the white rat basidiomycete Phanerochaete chrysosporium extensively mineralized the specifically [sup 14]C-ring-labeled azo dyes 4-phenylazophenol, 4-phenylazo-2-methoxyphenol, Disperse Yellow 3 [2-(4[prime]-acetamidophenylaso)-4-methylphenol], 4-phenylazoaniline, N,N-dimethyl-4-phenylazoaniline, Disperse Orange 3 [4-(4[prime]-nitrophenylazo)-aniline], and Solvent Yellow 14 (1-phenylazo-2-naphthol). Twelve days after addition to cultures, the dyes had been mineralized 23.1 to 48.1%. Aromatic rings with substituents such as hydroxyl, amino, acetamido, or nitro functions were mineralized to a greater extent than unsubstituted rings. Most of the dyes were degraded extensively only under nitrogen-limiting, ligninolytic conditions. However, 4-phenylazo-[U-[sup 14]C] phenol and 4-phenylazo-[U-[sup 14]C] 2-methoxyphenol were mineralized to a lesser extent under nitrogen-sufficient, nonligninolyticmore »« less
EFFECT OF X-RAYS ON DYE SOLUTION

Journal Article Matsuzawa, H; Nishino, T; Musha, K; ... - Kitakanko Igaku

Dye solutions such as triphenyl-methane, azo, anthraquinone, cyanine, thilasin, and nitro groups were exposed to x rays. The color of the aqueous and chloroform chloroform solution of these dyes faded or changed after the irradiation. THe chloroform solutions were more sensitive than the aqueous solutions. This may be attributed to the indirect action of the C1 atom produced from the chloroform. Cyanine and aminoazobenzene dyes which were very sensitive to irradiation may be of use for chemical determination of low radiation doses. (Abstr.Japan.Med.,1: No. 1, 1960)
Degradation of disperse blue 79 in anaerobic sediment-water systems

Conference Weber, E - Preprints of Papers Presented at National Meeting, Division of Water, Air and Waste Chemistry, American Chemical Society; (USA)

In recent years, concern over the environmental fate of the disperse azo dyes in natural water systems has grown. This concern arises from the fact that these dyes are very hydrophobic compounds, suggesting that they will partition strongly to bottom sediments where reductive cleavage of the azo linkage may occur. This transformation process could result in the release of potentially hazardous aromatic amines into the water column. Earlier studies in this laboratory demonstrated that the reductive cleavage of simple substituted azobenzenes in anaerobic sediment-water systems is a facile process. To determine whether reductive transformation of disperse azo dyes in naturalmore »« less
