Degradation of phenol from aqueous solution using waste blast furnace flue dust and hydrogen peroxide

摘要

A novel method to degrade phenol from simulated wastewater was studied using waste blast furnace flue dust with hydrogen peroxide (H2O2). The factors that affect the degradation efficiency, including the pH of the solution, the initial H2O2 concentration, the amount of blast furnace flue dust, the reaction temperature, and the reaction time, were studied. The experimental results show that 1,000mg/L of phenol in simulated wastewater can be decomposed completely within 12h by 15g/L blast furnace flue dust with 30mmol/L H2O2 in a solution whose pH was 3.0 at the temperature of 35 degrees C. The mechanism of phenol degradation was also investigated by high-performance liquid chromatography, X-ray diffraction, and UV-vis spectrum.
