Abstract

Subscript textThe degradation of Reactive Brilliant Blue KN-R by NaNO2/Fe3+/O2 system was evaluated. The optimal conditions of dye degradation by the NaNO2/Fe3+/O2 system were: reaction temperature 150°C, oxygen partial pressure 0.5Mpa, pH 3.0, Reactive Brilliant Blue KN-R /NaNOSubscript textSubscript text2/FeCl3 (mole ratio) equal to 1:2:0.2.Under the optimal conditions, the removal rates of color 、COD and TOC were 100% 、64% and 52%, respectively.
