dc.description.abstractThe present study investigates the results of decolorization of Malachite Green (MG), Reactive Black 5 (RB5), and Reactive Yellow 145 (RY145) in aqueous solutions based on a rapid and novel process of ultrasound-assisted ozonation. A Placket-Burman design (PBD) as a factorial design was used to quantify and screen the significant effects of the seven factors on decolorization efficiency: temperature (C-o), initial pH, probe position (height from bottom of reactor, mm), reaction time (min), ozone concentration (g/L), mixing speed (rpm), and ultrasonic power (W). Probe position and mixing speed were not found as significant after considering the regression and ANOVA results of PBD. A Box-Behnken design (BBD) as a kind of response surface methodology, with remaining five factors at three levels was set to demonsrate the interactions. The best-fit multi non-linear regression (MNLR) models were derived by using the results of BBD. According to BBD, the maximum decolorization efficiency of 99.31, 99.86, and 99.52% were obtained consistently at the lowest initial pH of 2, the highest reaction time of 30min, and ozone concentration of 0.15g/L for MG, RB5, and RY145, respectively. The best-fit MNLR models were cross-validated (R-pred(2)) accounting for 81.02-88.25% and were expressed (R-adj(2)) accounting for 93.01-95.70% of variation in decolorization efficiency.en_US
