Combined use of O3/H2O2 and O3/Mn2+ in flotation of dairy wastewater [PDF]
Ambiente e Agua - An Interdisciplinary Journal of Applied Science, 2018 This work investigated the degradation of organic matter present in synthetic dairy wastewater by the combination of ozonation (ozone (O3)/hydrogen peroxide (H2O2)) and catalytic ozonation (ozone (O3)/manganese (Mn2+)) associated with dispersed air flotation process.

Water Science and Technology, 1996 O3/vacuum ultraviolet (VUV, ultraviolet radiation by a low pressure mercury lamp at 185 and 254 nm), O3/H2O2 and VUV processes rapidly decomposed organophosphoric acid triesters (OPEs) dissolved in distilled water as compared to simple ozonation. The O3/VUV process was the fastest of the three advanced oxidation processes (AOPs) for the decomposition ...

Is O2*(a1Δg) Formed in the O+O3, H+O3, and NO+O3 Reactions ? [PDF]
Bulletin of the Chemical Society of Japan, 1980 Abstract An attempt was made to detect O2*(a1Δg) in the reactions of O+O3, H+O3, and NO+O3 using a photoionization mass spectrometer. No significant signals for O2*(a1Δg) were observed in these reactions. From the results, it is concluded that less than 0.06, 0.001, and 0.002 of the reactive collisions result in the production of O2 ...
