Abstract:
It is important to increase the efficiency of producing hydroxyl radicals with ozone
during the process of treating wastewater containing toxic and refractory organic
pollutants. In the present study, nickel oxide-loaded activated carbon (NiO/AC) and
copper oxide-loaded activated carbon (CuO/AC) were prepared with an incipient wetness
impregnation method at low temperatures. The effectiveness for degradation of phenol
and oxalic acid by the combination of NiO/AC or CuO/AC and ozone at different pH
values and concentrations of tert-butyl alcohol (t-BuOH) was investigated. The
composition and surface morphology of activated carbon (AC) and catalyst were
characterized by XRD, SEM, BET and AAS, which showed that copper and nickel were
loaded on the surface of AC in the form of rod-like copper oxide and nickel oxide. The
specific, micropore, and external surface areas and micropore volume of Cu/AC and
Ni/AC decreased by 50.7%, 62.9%, 34.8%, and 62.4% and 47.9%, 60.6%, 31.0%, and
60.7%, respectively. Compared to those of AC, in the systems of O3/Cu/AC and
O3/Ni/AC, the mechanism of degradation of phenol and oxalic acid by ozone was
achieved mainly by molecular ozone oxidation, while the mechanism with O3/AC was
primarily due to molecular ozone oxidation and absorption of AC. The removal
efficiencies of phenol and oxalic acid by O3/Cu/AC were 29% and 30.4% while those by
O3/Ni/AC were 52% and 59%. The efficiencies of both methods were higher than those
by ozone only. The degradation process occurred during the formation of hydroxyl
radicals and the reaction of Cu/AC or Ni/AC with ozone demonstrates the strong synergy
effect. The catalytic performance of Cu/AC and Ni/AC were stable, and both catalysts
were reusable for further catalyzation.
