1 Ozonation Research topics Investigation of Fenton-like system (e.g. Fe(II)/TPP/O2 system, Cu(II)/H2O2/Cl- system...) and synthesis of heterogeneous catalysts (e.g. Amor. FeTiOX, Ni-NiO) for effective organic pollutants degradationDevelopment and optimization of catalysis technology to effectively remove low-molecular weight organic pollutants for ultrapure water production Research and mechanism studies on high-valent metal species for selective organic pollutants removal Application of additives technology for improvement of oxidant utilization efficiency during soil remediation
