Abstract

Treatability of a model dye, cuprophenyl yellow RL, in wastewater by the UV/H2O2/Ultrasonication (US) process was studied on a bench-scale UV/US combined reactor. The effects of pH, hydrogen peroxide dosage and US on the oxidation process were investigated, and the performance of the process on colour removal were evaluated. It was found that degradation of the dye followed a pseudo-first-order kinetic model at different pH and hydrogen peroxide dosages. The relationships between the rate constants and pH as well as hydrogen peroxide dosages were established.
