Ozone and Chlorine Degradation of Wastewater Pollutants.

摘要

An attempt was made to compare the effectiveness of chlorination and ozonation on the removal of a variety of organic compounds from solutions. Both ozone and chlorine concentrations were measured using the orthotolidine-manganese sulfate (OTM) method;concentrations were measured spectrophotometrically,and thin-layer and gas-liquid chromatography were used to evaluate oxidation products and concentrations. Both chlorine and ozone are effective but vary greatly in their activity and specific reactions. Chlorine at 3times conc. was not effective against amino acid proline, p. dioxane,diphenylamine,guanidine, n-hexane,phenol,and pyridine. Ozone was very destructive to the fatty acids levulinic,linoleic and oleic acids. This explains a part of ozone germicidal activity.
