     feasibility of ozone oxidation for the elimination of selected dissolved organic micropollutants from water and wastewaters was studied. five organochlorine pesticides, i.e. hexachlorobutadiene, pentachlorobenzene, hexachlorobenzene, lindane, and heptachlor, were used as organic contaminants of model water. the first four of them are classified as priority hazardous substances. the oxidation treatment process was performed in a jet loop reactor. ozone was prepared from pure oxygen. quantification of the organochlorine pesticides in water was achieved by the gas chromatographic method after liquid-liquid extraction. significant contribution of stripping to the removal of the investigated compounds during the ozonation treatment was also proven by the results. effective ozonation time with regard to treatment efficiencies was 30 min, which corresponds to the ozone input of 317 mg per liter of active volume of the ozonation reactor. single power law kinetic models were used to describe experimental data and kinetic parameters were estimated. the best fit of the experimental degradation data of all studied pollutants was obtained by the second order kinetic model. it can be concluded, based on the results obtained, that the applied ozonation process is a promising procedure for the removal of the investigated pesticides from aquatic environment.
