Concentration dependence of thermal isomerization process of methyl orange in ethanol [PDF]

open access: yes, 2017
The thermal isomerization (TI) rates of methyl orange (MO) and 4-dimethylaminoazobenzene (DMAAB) in ethanol (EtOH) are measured. Usually TI rates of azobenzene dyes are known to be concentration independent.

Potential and prospects of reductases in azo dye degradation: a review

open access: yesThe Microbe
Synthetic dyes, particularly azo dyes, pose environmental and health risks because of their toxicity and persistence. To reduce these negative effects, it is necessary to degrade and detoxify these dyes into simple, non-toxic substances.
