More efficient oxidation methods are needed to degrade especially newly emerging recalcitrant organic contaminants at. low concentrations in the water environment. Reduced photonic efficiency of immobilized TiO2 is a major challenge in TiO2-assist...
Even though O3/H2O2 based AOP has been proven to be an effective polishing treatment for sewage effluent, some of organic compounds were still found after treatment as the TOC value of treated sample was around 1 mg/L. In pursue of identifying the...
