Comparison Of The Efficiency Of Ozonation And Catalytic Ozonation (mn Ii And Cu Ii) In Phenol Degradation [comparação Da Eficiência Do Processo De Ozonização E Ozonização Catalítica (mn Ii E Cu Ii) Na Degradação De Fenol]

This paper discusses the results obtained with homogeneous catalytic ozonation [Mn (II) and Cu (II)] in phenol degradation. The reduction of total phenols and total organic carbon (TOC) and the ozone consumption were evaluated. The efficiency in phenol degradation (total phenol removal) at pH 3, with the catalytic process (Mn (II)), increased from 37% to 55% while the TOC removal increased from 4 to 63% in a seven-minute treatment. The ozonation process efficiency at pH 10 was 43% and 39% for phenol and TOC removal, respectively. The presence of both metallic ions (Mn 2+ and Cu +2) in the ozonation process resulted in a positive effect.
