Can deuterium be separated from heavy water via electrolysis? It is an isotope of hydrogen, so I guess it should act in the same way?
I was wondering if it is possible to separate deuterium from heavy water via electrolysis.
Also, is this the way deuterium gas is obtained on an industrial scale, or are there better methods?
