Chemical transformations in treatment of saline solution with ozone-oxygen gas mixture

This paper contains the analysis of published reference data related to the ozone and NaCl interaction in aqueous solutions with different content of NaCl (0.9%, 1%, 3%, 5%, and 10%) therein and their bubbling by the ozone-oxygen gas mixture with the ozone concentration ranging from 10 to 100 mg/l within 10 to 120 minutes. The authors of the papers under study by using the protonography, chemical, spectrophotometric, and cristalloscopic research methods identified in ozonated solutions potentially possible products of the ozone and sodium chloride reaction in water: hexagonal aqueous structure, sodium hypochlorite, hypochloric acid, chlorates (ClO–, ClO2–, ClO3–), nitrite, nitrate (NO₂^– and NO₃^–), free radicals, hydrogen peroxide, as well as dissolved ozone and oxygen. From the performed analysis of published reference data it follows, that when treating these solutions with the ozone-oxygen gas mixture and in the subsequent disintegration of ozone therein, the latter interacts neither with Na+ nor with Cl–; sodium hypochlorite and other chlorine-containing oxygen ions, nitrates, and nitrites are not formed herewith. There are identified dissolved oxygen and ozone, and in the interaction of the latter with water free radicals, hydrogen peroxide, hexagonal, and low-molecular aqueous structures are generated.
