A water supply borehole in the Sherwood Sandstone aquifer in Warrington, UK was found to be infested with iron bacteria that resulted in large ochreous deposits and damaged the pump. Before the pump was replaced, the borehole was treated using hydrogen peroxide. Comparison of the borehole ...
Trihalomethanes (THMs) the by-products of chlorination in water treatment are recognised as a threat to public health due to their carcinogenicity. The photodegradation of THMs using hydrogen peroxide has been found to give increased removal efficiency and the outcome of the study may find, its ...
yields hydrogen peroxide (H2O2), which is consumed by reactions with radicals and by thermal decomposition according to the following sequence:(3.37)H2O2+OH→H2O+HO2(3.38)H2O2+H→H2O+OH(3.39)H2O2+H→HO2+H2(3.40)H2O2+M→2OH+M From the sequence of reactions (3.37)–(3.40), one finds tha...
The efficiency of bicarbonate/carbonate as a promoter for the radical-based chain reaction in presence of hydrogen peroxide has been calibrated and compared to a well-known chain promoter (methanol) and an inhibitor (tert-butanol). Relative to tert-butanol, the hydrogen peroxide induced ozone ...
3.4.1Hydrogen peroxide Hydrogenperoxideis a unique and most important covalent peroxide. Many of its physical properties resemble those of water. However, chemically, it is very much different from water. It is not as stable as water. It decomposes into water and oxygen upon heating or in the...
Interaction of ozone and hydrogen peroxide in water: Implications for analysis of H2O2 in air We have attempted to measure gaseous H2O2 in air using an aqueous trapping method. With continuous bubbling, H2O2 levels in the traps reached a plateau, in... Rod,G.,Zika,Eric,... - 《Geophysical...
Acidic and hydrogen peroxide treatment of polyaluminum chloride (PACL) sludge from water treatment. Water Sci Technol, 50(9), 99--105.Acidic and hydrogen peroxide treatment of polyaluminum chloride (PACL) sludge from water treatment. Kwon J H,Park K Y,Park J H,Lee S H,Ahn K H. Water...
The method in the invention is as follows: introducing ozone and hydrogen peroxide beforehand into the raw water before conventional processing, wherein, the introduction amount of ozone in each liter of raw water is 1.6-2.2 mg, the dosage of hydrogen peroxide is 5-10 mg, and the retention ...
hydrogen peroxide- a viscous liquid with strong oxidizing properties; a powerful bleaching agent; also used (in aqueous solutions) as a mild disinfectant and (in strong concentrations) as an oxidant in rocket fuels peroxide oxidant,oxidiser,oxidizer,oxidizing agent- a substance that oxidizes another...
Hydrogen peroxide is an oxidizing agent, known not only for its high oxidation potential, but its strong performance across a wide pH range as well. The extreme versatility of this clear liquid gives rise to a growing number of applications, including: Generating cleaner water, air and soil ...
