WebThe deuterium in the hot loop slightly prefers to be in the hydrogen sulfide, resulting in excess deuterium in the hydrogen sulfide relative to the cold tower. For n moles of deuterium per mole of protium in the hot tower input water, there is n 1.82 moles per mole of deuterium in the hydrogen sulfide. WebFortunately, deuterium is common. About 1 out of every 5,000 hydrogen atoms in seawater is in the form of deuterium. This means our oceans contain many tons of deuterium.
