Investigation on the Removal of COD from Colored Aqueous Solutions with O-3, H2O2, HCO3-, and PAC
Özet
In this study, chemical oxygen demand (COD) was removed using different processes containing O-3, H2O2, HCO3-, and powder activated carbon (PAC) from the synthetic dye solutions. The effects of the experimental parameters such as temperature, ozone dose, dye concentration, pH, and time on the removal of COD were investigated. The Taguchi method was applied to determine the optimum conditions. An orthogonal array L-18 (2(1) * 3(7)) experimental design plan was selected to define the optimum conditions. In addition, the mechanism of the COD removal was explained on the basis of the results of Fourier transform infrared (FTIR) spectroscopy. To gain information about COD removal mechanism at various pHs, electrophoretic mobilities of particles were measured. The chosen experimental parameters and their ranges are:
