Deuterium from seawater
The name deuterium is derived from the Greek deuteros, meaning "second", to denote the two particles composing the nucleus. Deuterium was discovered by American chemist Harold Urey in 1931. Urey and others produced samples of heavy water in which the deuterium content had been highly … See more Deuterium (or hydrogen-2, symbol H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium, or hydrogen-1). The nucleus of a deuterium atom, called a deuteron, contains one See more Data for molecular deuterium Formula: D2 or 1H 2 • Density: 0.180 kg/m at STP (0 °C, 101325 Pa). • Atomic weight: 2.0141017926 Da. • Mean abundance in ocean water (from VSMOW) 155.76 ± 0.1 atoms of deuterium per million atoms of … See more An antideuteron is the antimatter counterpart of the nucleus of deuterium, consisting of an antiproton and an antineutron.

WebAug 31, 2024 · Extracting this deuterium from seawater is a simple and well proven industrial process. “Heavy water”, or D2O (water in which deuterium substitutes for hydrogen), is first separated from regular water by chemical exchange processes, and is then submitted to electrolysis in order to obtain deuterium gas.
WebMar 1, 1978 · Since the deuterium concentration in seawater is as low as 158 ppm, almost all of the deuterium exists in the form of HDO, instead of DaO (2). Therefore, one must notice the vapor-liquid equilibrium of only HDO, or the relative volatility of HDO and HzO. Equilibrium concentration ofHaO, HDO and DaO is shown in Fig. 3. 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 …

Webdeuterium isotope ratio, dD, and the water vapor mixing ratio, Q, were measured for 11 pairs of samples collected on three summer days. Remarkable gradients of dD and Q existed across the two sampling heights at 0.5 m and 3.0 m. The mixing line method was used to derive the deuterium isotope flux ratio, dD F, which characterizes the
