What is DEUTERIUM?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is DEUTERIUM which has developed particularly rapidly in recent years. Do you know about DEUTERIUM?
- The official answer: Deuterium is the isotope of hydrogen, also known as heavy hydrogen, the chemical symbol is D or 2H, deuterium at room temperature is a colorless, odorless flammable gas, the abundance on the earth is 0.015%, its content in the general hydrogen is very small, and most of the heavy water D2O that is, deuterium oxide in the form of seawater and ordinary water.Deuterium is an isotope of hydrogen, composed of a proton, a neutron and an electron, discovered in liquid hydrogen by H.C. Yuri and F.G. Brickwider in 1931. The mass concentration of deuterium in seawater is approximately 30 mg/L. Deuterium gas has a wide range of applications in military, thermonuclear experiments and optical fiber manufacturing.
What’s the application of DEUTERIUM?
In terms of “imports”, the raw materials for reactions required for controlled nuclear fusion (deuterium atoms and tritium atoms) are very abundant on Earth. Deuterium reserves in seawater are extremely large, once the thermonuclear fusion experimental reactor is successfully studied, it can use seawater to generate electricity, and the energy released by one liter of deuterium extracted from seawater through fusion reaction is equivalent to 300 liters of oil. Tritium, on the other hand, can be formed by reacting neutrons with lithium, which is abundant in both the earth’s crust and seawater.Hydrogen lamps and deuterium lamps are commonly used light sources in the ultraviolet region, they produce continuous radiation in the wavelength range of 180 to 375 nm, under the same operating conditions, the emission intensity of deuterium lamps is about 4 times greater than that of hydrogen lamps. Glass has a strong absorption of radiation in this wavelength range and must use quartz light windows. The UV/VIS spectrophotometer is equipped with both UV and visible light sources.
