I am working on treatment textile wastewater with two dyes Acid blue (Ab113) and Basic Red (BR46).
Dear Fadhel,
we working on degradation of AB113 by Advanced Oxidation Processes. Do you need measured only aromatic amines in compounds, or you need measured only concentration of dyes? I dont know what is your purpose. AB113 has maximum at wavelength 574 nm. You can check UV-VIS spectrum between 350 and 800 nm and from maximum peak create a calibration curve.
Here is also our publication. Unfortunately is in Slovak language, but maybe it will be usefull.

Lukáš Hrdlička Many thanks for your answer, I need to know what is wavelength for aromatic amine, I need to measure the aromatic amine in compound?
If you form amines from the azodye I assume you are using a type of reductive treatment such as zero valent iron. As the azo group is reduced the color is lost. I don't think the product has a clear color.
You could try out to use the colorimetric reaction for aniline that we use to quantify reduction of nitrophenol in the linked paper. It should give a good color that is read at around 680 nm. Briefly the color is developed by first adding hypochlorite and after 15 min reaction time adding NH4+ with a little sodium nitroprusside.

Aromatic amines gives peak in range of 200-700 nm. u can can check in that range. various amine ranges are given in attachment .
Hi Srithar,
I am treating textile azo dyes by using constructed wetlands and I am fine with COD date, I think the paper that I uploaded on my page included an answer for your question.
