Oxidizing purification of water using thermal plasma

The generation of atoms and radicals by the equilibrium thermal dissociation of oxygen and the same process involving water vapor are similar in terms of the reactive-species yield and energy consumption. The energy input into the generation of atoms and radicals is the smallest at 4500 K; about 70% of the energy is spent directly for the breaking of chemical bonds. From the calculations of the kinetics of oxygen atom recombination, it follows that cooling at a rate higher than 10⁷ K/s makes it possible to achieve considerable deviations from the equilibrium atom concentration. The lifetime of atoms in cooling thermal plasma is estimated at 10^?5 s. It has been established experimentally that a thermal plasma jet plunging into the water bulk generates hydrogen peroxide. The totality of factors affecting the hydrogen peroxide accumulation rate can be represented in as a generalized parameter, specifically, the atomic oxygen feed rate.
