Kinetics of Reactive Blue 21 Decolorization Using Peracetic Acid

Abstract

Decolorization rate of Reactive Blue 21 by peracetic acid in aqueous solutions was
measured at pH 6.0. Concentrations of peracetic acid were applied in the range of 1 - 3 mM. The
reaction kinetics were monitored by recording the light absorption of the Reactive Blue 21 at 660 nm.
The obtained results showed that the decolorization happened via non-catalytic and auto-catalytic
reactions. Both the reactions were proposed to obey the second-order rate law.
