Abstract
Docolorization of Methylene Blue was investigating using a Ultrasonic/Fenton like reactor in batch mode. The effects of pH, reaction time, initial concentration of dye, H2O2 and Fe on the dye removal was studied. It was found that the increase of initial dye and H2O2 concentration and the increase of initial pH, are not beneficial for improving the dye removal efficiency. Increasing the dye concentrations from 50 to 400 mg/L resulted in decreasing the rate of decolorization from 0.255 to 0.063 min-1, respectively. Complete removal (100%) was observed, when pH, reaction time, initial concentration of dye, H2O2, Fe and ultrasound density were found to be 3, 30 min, 100 mg/L, 200 mg/L, 25 mg/L, 40 kHz, respectively. The results showed that H2O2/Fe° equal 8 is more effective for dye removal.
