Oxyozosynthesis is a pressurized ozone–oxygen oxidation flotation process, which involves the use of ozone and oxygen as the oxidation agents for stabilization of wastes in a pressurized reactor to expedite the oxidation process. The wastes can be either a wastewater stream or a sludge stream (...
Ozone is formed by photolysis of oxygen in the stratosphere and diffuses down through the troposphere to be destroyed at the Earth's surface. Its concentration at cloud-forming levels is several times greater than pollutant gases such as SOand NO. It is known that ozone reacts rapidly with ...
Nitrogen oxides (NOx = NO + NO2) emitted from combustion and natural sources are reactive gases that regulate the composition of Earth’s atmosphere. Nocturnal oxidation driven by nitrate radicals is an important but poorly understood process
The gas-phase oxidants mainly include ozone, oxygen, air, water vapor, carbon dioxide, etc. Due to differences in the thermal stability of oxygen-containing functional groups, the type and content of oxygen-containing functional groups produced by gas-phase oxidation strongly depend on the oxidation...
Ozone is a bluish gas with a pungent smell and is an extremely reactive and unstable allotrope of oxygen (O2). The physical properties of ozone are listed in Table 2 (compiled from [2]). Table 1. Typical Advanced Oxidation Processes (AOP). H2O2/UVFe2+/H2O2(Fenton System)O3/H2O2 O3/...
Thermodynamics of oxidation of crystalline silicon carbide (cubic form) by atomic oxygen (O) and ozone (O3) was derived to understand the thermodynamic stability of SiC in the upper atmosphere. Equilibrium constants and equilibrium partial pressures were computed for each of eight possible reactions ...
As the bubble diameter reaches micrometers or even nanometers, the surface tension of the gas–liquid interface compresses the bubbles, thus increasing the specific surface area of bubbles and the oxygen transfer efficiency between gas and liquid [8]. The diameter of MBs is small and the ...
In this degradation method, sodium chloride was used as an electrolyte, and the mixture was passed through an electrolytic cell. A high rate of color removal was obtained due to the production of highly reactive strong oxidizing potentials of chlorine, oxygen, hydroxyl radicals, and other oxidant...
Fresh milk, produced in the normal way, exhibits a potential at a gold or platinum electrode of between +0.20 and +0.30 V, which is largely attributed to dissolved oxygen. Milk is essentially oxygen-free when secreted, but about 0.3 mmol l-1 O2 are present after equilibrium with air is ...
In addition, since ozone produces only oxygen by decomposition thereof, and therefore ozone is environmentally friendly, use of ozone has tended to increase in recent years. A method for improving effects of such an ozone treatment usually involves increasing the amount of ozone used. However, an...
