A purification system for nitrogen gas and xenon gas in water and a static isotopic analysis method thereof are provided. The system includes a sample container, a carbon dioxide ice cold trap, a gas delivery main pipe and a mass spectrometer for noble gas communicated sequentially. The gas delivery main pipe is provided with branch pipelines communicated with a cryo pump and a vacuum pump set respectively, the mass spectrometer for noble gas is communicated with the vacuum pump set, and the cryo pump adsorbs or releases nitrogen gas and/or xenon gas by setting different temperatures of the cryo pump. Inlet and outlet sides of the carbon dioxide ice cold trap are respectively provided with a first valve and a second valve. Fourth and fifth valves are respectively disposed between the gas delivery main pipe and the vacuum pump set, and between the gas delivery main pipe and the cryo pump.

An apparatus and method for separating tritiated water (HTO) and/or heavy water (D20) from light water (H2O). A disposable, dense, plastic filter mesh is disposed within a cylinder which is configured to rotate. Chilled heavy water is pumped into the rotating cylinder. Tritiated heavy water, which is preferably frozen, is pressed to the interior wall of the cylinder which is lined with the filter mesh. The heavy water becomes affixed to the mesh, and light water is drained from the cylinder to be reused as coolant. The mesh filter, when needed, is safely disposed in accordance with industry guidelines. The mesh filter is then replaced with a new iteration of the filter.

A method for recovering isotopologues from a gas stream is provided with a wet scrubber column, which includes a liquid inlet, a liquid outlet, a gas inlet, a gas outlet, and a plurality of bubble cap trays. An initial gas stream is enriched with isotopologues, while an initial aqueous liquid is depleted of isotopologues. The initial gas stream is countercurrently contacting the initial aqueous solution through the bubble cap trays as the initial gas stream traverses from the gas inlet to the gas outlet and as the initial aqueous liquid traverses from the liquid inlet to the liquid outlet. A processed gas stream is then captured from the gas outlet and is depleted of isotopologues. Simultaneously, a processed aqueous liquid is captured from the liquid outlet and is enriched with isotopologues.

A process and system for treating fluid comprising water, radioactive particulate, dissolved ions, and a neutron absorber are provided. The fluid is received from a cutting zone for recover), of radioactive components. The process comprises receiving a fluid in a crystallization unit, the fluid comprising the water, the radioactive particulate, and the neutron absorber dissolved in the fluid; cooling the fluid below a freezing point of the fluid to form a first crystal comprising the water and to form a second crystal comprising the neutron absorber, the second crystal having a greater density than the first crystal; and separating the first crystal from the second crystal, the radioactive particulate, and the dissolved ions.

Water-based compositions suitable for the hydration of a mammal, and particularly hydration of a human by oral or topical methods, and for industrial uses such as cooling, and the making of solutions and mixtures. A method for producing a beverage, an industrial process water, an industrial solvent, or topical dermatological composition includes: providing a water source, the water molecules having oxygen or hydrogen atoms of different isotopes, (i) fractionating the water source to produce a fraction enriched in water molecules having an abundance of at least one of the oxygen or hydrogen isotopes being greater or less than the abundance found in the water source, or (ii) where the water source is already enriched in heavy water, fully or partially maintaining the level of enrichment.

Provided is an industrially feasible method for separating tritiated water from contaminated water. The method for separating tritiated water from light water contaminated by the tritiated water, includes the steps of; adding heavy water to the contaminated water; converting the liquid mixture of the contaminated water and the heavy water into a mixture of the light water and a gas hydrate consisting essentially of the tritiated water and the heavy water as the crystal structure under a condition of converting into the gas hydrate of at least one of the heavy water and the tritiated water, and yet keeping most of the light water in liquid state; and separating the gas hydrate from the light water.
