Two-steps process of the activated Brilliant Orange - KR and photocatalysis oxidation
Online published: 2010-10-01
The decolouration, flocculation and photocatalysis conditions of the activated dye, activated Brilliant Orange KR have been studied. After it is treated by iron powder, the pH value is adjusted, and flocculation is sedimentated, the activated Brilliant Orange KR should be treated by photocatalysis and oxidation degradation. Then, its COD removal rate can reach 85% ~ 92%. The catalysis of TiO2, which is used as photocatalysis oxidation catalyst, is reinforced due to the additing of iron powder, and forming Fe ions in the solution. Therefore, this is an efficient degradation. It is practical for production.
