Kinetics of anaerobic biodecolourisation of azo dyes.
Kinetics of anaerobic biodecolourisation (methanogenic environment) of four azo dyes (Acid Orange 6, Acid Orange 7, Methyl Orange and Methyl Red) was investigated with regard to their electrochemical properties as well as under variation of dye and sludge concentrations, pH and temperature. Cyclic voltammetry revealed a correlation between the potential of irreversible reduction peak of the dye...
متن کاملRemoval of Dyes from Textile Industry Effluent: A Review
Effluent from the textile industry contains toxic compounds. These compounds contaminate the surface water, thereby making it unfit for irrigation and drinking. Since farmers use water from the rivers for agricultural purposes and the residents of the town, use both the surface and underground water from the same area as potable water, it is quite unsafe to discharge this effluent into water bo...
متن کاملBiological Removal of Azo and Triphenylmethane Dyes and Toxicity of Process By-Products
Increasing environmental pollution is connected with broad applications of dyes and imperfection of dyeing technology. Decolourization of triphenylmethane brilliant green and disazo Evans blue by bacterial and fungal strains and toxicity (phyto- and zootoxicity) of degradation by-products were investigated. Influence of incubation method on dyes removal was evaluated (static, semi-static, shake...
متن کاملNew copolymer of acrylamide with allyl methacrylate and its capacity for the removal of azo dyes
The copolymerization reactions of Acrylamide (AA) with the different mole ratios of allyl methacrylate (AMA) such as 25/75, 50/50 and 75/25 were studied by radical polymerization under argon atmosphere using 2,2’-Azobis (isobutyronitri1e) (AIBN) as initiator. The copolymers were characterized with Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TG). FTIR spectra s...
متن کاملStructure and carcinogenic activity of azo dyes.
In recent years many investigations have been carried out on the carcinogenic activity of several groups of derivatives of 4-aminoazobenzene, their spectra, the relative basicities of their nitrogen atoms, and their metabolism (1, 2, 9, 14). The principal results on the correlation of structure and activity are as follows: Methylation.--3'-Methyl-4-dimethylaminoazobenzene is a tvery potent carc...
