D2o is used in
WebDeuterium oxide is routinely used in the process of heavy water electrolysis for production of deuterium gas that is essential for semiconductor industries. For example, replacing hydrogen with deuterium greatly reduces hot electron degradation effects in metal oxide semiconductor transistors due to isotope kinetic effect. WebThis procedure is often used with the water, due it allows to determine the mobile protons (OH, NH, SH etc...) that in D2O exchange the H with D and are not determinable. Cite 1 …
