Decolourization of an azo dye in aqueous solution by ozonation in a semi-batch bubble column reactor
(Science Society of Thailand under Royal Patronage, 2015-02)
The oxidative degradation of the azo dye Reactive Red 120 by ozonation was investigated. The decolourization was carried out by bubbling ozone at the bottom of a bubble column reactor containing the dye solution. The colour, ...
Characteristic of COD and colour removal of azo dye in ozonation and biological treatment
(Institute of Electrical and Electronics Engineers (IEEE), 2011)
In this research, the characteristic of COD and colour removal of azo dye by ozonation and biological treatment was evaluated for applying in azo dye industrial effluent treatment. Reactive Red 120, Remazol Brilliant Blue, ...
