Removal of Selected Organochlorine Compounds by Ozone-based Processes
The paper is focused on the possibility of using ozonation process combined with iron nanoparticles (nZVI – nano zero-valent iron) to remove selected specific synthetic substances, such as hexachlorobutadiene, pentachlorobenzene, hexachlorobenzene, lindane and heptachlor.

| description | The paper is focused on the possibility of using ozonation process combined with iron nanoparticles (nZVI – nano zero-valent iron) to remove selected specific synthetic substances, such as hexachlorobutadiene, pentachlorobenzene, hexachlorobenzene, lindane and heptachlor. Experimental measurements were performed in order to evaluate the effectiveness of the removal of substances and their removal rates. Removal of pesticides was also monitored through calculated DOC (dissolved organic carbon) as cumulative wastewater quality indicator. We investigated the effectiveness of 5 mL L–1 nZVI suspension (equal to 1 g Fe0) for the optimization of micropollutants removal from model water. Applications of 5 mL L–1 nZVI suspension and combined O3/nZVI processes have been shown as the most effective. Increasing concentrations of nZVI had almost no impact on the efficiency of the degradation process. Higher degradation efficiencies of γ-HCH were measured in O3/nZVI compared to the ozonation process. Degradation of pesticides HCLB, HCLBD and PCLB in all tested processes achieved efficiencies above 88 %. |
