Paper Title:
Oxidation Decoloration Kinetics of C.I. Direct Blue 108 in Activated Oxygen Bleach Systems
  Abstract

The decoloration behaviors of C.I. Direct Blue 108 in two activated oxygen bleach systems (PB/TAED and PC/TAED) were investigated. It was found that the decoloration kinetics of the dye in the two systems followed the first-order kinetic model and the rate constants calculated by linear regression increased significantly with increasing temperature. The activation energies for the decoloration in PB/TAED and PC/TAED systems were 63.34 and 58.10 kJ/mol, respectively. Moreover, the highest decoloration rate constant was obtained at pH 9 in the two systems. The kinetic model had not changed with temperature and pH in the two systems.
