Extract deuterium from any surface water
WebJul 10, 2024 · Deuterium excess (d-excess) is a function of the isotopic composition of oxygen (δ 18 O) and hydrogen (δD) in water (d-excess = δD − 8 × δ 18 O) [ 7 ]. Isotopic ratios are expressed as δ values which are deviations in per mil (‰) from a … WebDeuterium density in seawater. I heard today that deuterium for nuclear fusion could be extracted from the Oceans, in which it is present in "heavy water." I heard this claim: "Deuterium is distributed uniformly with Ocean depth." This contradicted my naive expectation that deuterium density would increase with depth, on account of it being in ...
