Abstract

Decoloration reaction of Orange II and Reactive Blue 2 were investigated to rice hull peroxidase (RPO) bleaching system in the presence of sodium percarbonate (PC) system by measuring the decoloration rate, decoloration rate constants and the color difference of transfer to fabrics. Decoloration rate constant of Orange II in the RPO-PC system increased 2.2 times higher compared with that of RPO single system, when H2O2 concentration is high such as 300 mM in the model bleaching system. Decoloration rate of Orange II also increased in the RPO-PC system, it occurred 100% in the RPO-PC system in comparison with 95 % that of RPO single system. HPLC analyses of decoloration products of the Orange II in RPO-PC system, peaks of all colored products disappeared. In addition, using RPO-PC system, it is possible to decompose Reactive Blue 2 dye having a refractory structure. In the nylon fabric washing model, it is possible to inhibit for dye transfer with RPO-PC system, no matter how low PC concentration of 10 mM is added.
