Problems solved by technology

[0008] The glaciers are located on the plateau away from human habitation, the cost of mining and transportation is huge, and the deuterium content is not much different from that of ordinary water, so there is no large-scale mining and utilization so far
The method of water rectification, also because the boiling point difference between water and heavy water is very small, consumes a lot of energy, and there is no mass production. It is only a by-product of deuterium-depleted water in the oxygen-18 production device, and the output is very limited.
The energy consumption of electrolyzed water is high, and the production cost is also relatively high. So far, there have been no reports of large-scale production

Abstract

The invention discloses a method for producing deuterium-depleted water. Activated aluminum oxide supported nano platinum is taken as a specific adsorbent and is placed in a long and thin adsorber with the diameter of 8-50mm and the length of 0.1-10km, low-cost efficient mass production of deuterium-depleted water is realized, and adsorber equipment used for mass production can realize continuous production of the deuterium-depleted water by heating and cooling, so that the production efficiency is greatly improved, the production cost is reduced, and the enterprise competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of stable isotopes, in particular to a method for producing deuterium-depleted water by adsorption. Background technique [0002] Deuterium-depleted water, English name deuterium depleted water, DDW for short. Deuterium-depleted water with low deuterium content is called light hydrogen molecule water. [0003] Water that exists in nature is composed of 2 hydrogen atoms and 1 oxygen atom, but the hydrogen atom has 3 isotopes with different masses, hydrogen (H), deuterium (D, heavy hydrogen), atomic weights 1, 2, and 3 respectively Tritium (Triotium). In natural water, the content of deuterium is about 150ppm (the number of moles of deuterium / the number of moles of hydrogen + deuterium + tritium), and the content of tritium is very small. The water combined with D instead of H is heavy water. Studies at home and abroad have shown that deuterium is harmful to the survival, development and reproduction of liv...
