Picosecond Switchable Azo Dyes
Chemistry – A European Journal, 2019AbstractAzo dyes that combine electron‐withdrawing thiazole/benzothiazole heterocycles and electron‐donating amino groups within the very same covalent skeleton exhibit relaxation times for their thermal isomerization kinetics within milli‐ and microsecond timescales at room temperature.

Degradation of azo dyes by algae
Environmental Pollution, 1992The degradation of azo dyes by algae was evaluated and it was found that certain algae can degrade a number of azo dyes to some extent. The reduction rate appears to be related to the molecular structure of the dyes and the species of algae used. The azo reductase of algae is responsible for degrading azo dyes into aromatic amine by breaking the azo ...

Bioreactors for Azo-Dye Conversion
2010This chapter embodies two sections. In the first section a survey of the state of the art of azo-dye conversion by means of bacteria is presented, with a focus on reactor design and operational issues. The relevance of thorough characterization of reaction kinetics and yields is discussed.

Abstract Any liquid azo dyes, in which auxochrome such as dialkylamino, alkoxy, and amino group is attached in a molecule, were produced. In a series of 2-alkyl-4’-(dimethylamino)azobenzenes, the butyl, hexyl, octyl, and dodecyl derivatives were liquid at room temperature, whereas the propyl, 1-methylethyl, 1-methylpropyl, 1,1-dimethylethyl, and ...

Journal of the Society of Dyers and Colourists, 1956
Twenty‐one water‐soluble azo dyes– mono‐, bis‐, tris‐, and tetrakis‐azo, selected from the acid, basic, mordant, and direct dyeing classes–have been examined by polarographic methods. The object was to determine how far these methods could be used for the identification and estimation of azo dyes in general.

Decolorization of Azo Dyes in Bioelectrochemical Systems
Environmental Science & Technology, 2009Azo dyes are ubiquitously used in the textile industry. These dyes need to be removed from the effluent prior to discharge to sewage due to their intense color and toxicity. In this study we investigated the use of a bioelectrochemical system (BES) to abioticlly cathodic decolorization of a model azo dye, Acid Orange 7 (AO7), where the process was ...
