Experimental studies on application of potassium ferrate for 3-methylphenol removal from solution in laboratory
With a series of experimental studies on oxidation by using potassium ferrate for removal of 3-methylphenol (m-cresol) in the laboratory,the results showed that the removal efficiencies were definitely impacted by pH values,initial concentration of 3-methylphenol solutions and added K2FeO4 dosage.The optimal pH values needed to be controlled at two intervals at 5.0-6.0 or 9.0 respectively when the advantageous input of K2FeO4 should have a mole ratio about 4∶1 or 3∶1 to 3-methylphenol concentrations.At pH6.0 and 20℃,the maximum removal of 3-methylphenol with the initial concentrations of 50-300mg/L could reach 70%if the mole ratio between the added K2FeO4 and 3-methylphenol was 3∶1 in the solution during the reaction time of 30min.The existence of inorganic salts such as MgSO4 could significantly affect the removal rates,for instance,the removal of 3-methylphenol could be enhanced by 25% if adding MgSO4.into the reaction solution.
