Abstract
Destruction of Azo-Reactive Dyes by Ozonation and the Synergetic Effect of a Radio-Frequency Alternating Electric Field Inductance Device
Highlights
Ozone, the triatomic, allotropic form of oxygen is a very powerful oxidant with many commercial and industrial applications
The oxidizing action of ozone in aqueous solutions is rather complex since ozone acts by several mechanisms, including the presence of other highly strong oxidizing agents, like atomic oxygen (|O|), perhydroxyl (HO2), or hydroxyl (OH) free radicals
The Radio-Frequency Alternating Electric Field (RFAEF) inductance device was connected with the bubble column reactor by means of a copper ring electrode that was attached on the external surface of the reactor; just under the top of the water level (Figure 3)
Summary
The triatomic, allotropic form of oxygen is a very powerful oxidant with many commercial and industrial applications. The considerable oxidizing power of ozone and its molecular oxygen by-products make it a first choice for oxidation or disinfection over the many various chemical alternatives It is one of the most active, readily available oxidizing agents that can be generated on-site. The oxidizing action of ozone in aqueous solutions is rather complex since ozone acts by several mechanisms, including the presence of other highly strong oxidizing agents, like atomic oxygen (|O|), perhydroxyl (HO2), or hydroxyl (OH) free radicals. Both direct and indirect oxidation reactions occur. One kind of reaction usually dominates, depending on various factors, such as temperature, pH, and chemical composition of the aqueous solution [1,2,3]
