Effect of buffer on orange II degradation by the peroxidase-hydrogen peroxide bleaching system
Abstract One of the latest bleaching systems is the degradation of Orange 2 by peroxidase (POD)-hydrogen peroxide (H2O2) bleaching. We studied the effect of buffer solutions with this bleaching system, which changed the decoloration rate of Orange 2. With the Carmody buffer, the total reaction time...

Summary: | Abstract One of the latest bleaching systems is the degradation of Orange 2 by peroxidase (POD)-hydrogen peroxide (H2O2) bleaching. We studied the effect of buffer solutions with this bleaching system, which changed the decoloration rate of Orange 2. With the Carmody buffer, the total reaction time was 60 min. With the Tris/HCl buffer, the total reaction time was 40 min. We consider that the difference in the decoloration rate of Orange 2 in peroxidase-hydrogen peroxide bleaching system was increased reactivity caused by Tris and decreased reactivity caused by the citric acid. |
