Introduction
Greetings, esteemed readers! Are you curious about how heavy water is made? If so, you’ve come to the right place. In this article, we will delve into the fascinating process of producing heavy water and its advantages and disadvantages.
Heavy water, also known as deuterium oxide, is a type of water that contains a higher amount of the isotope deuterium than normal water. This makes it a valuable resource in various industries, including nuclear power, chemistry, and medicine. But how is this specialized water produced?
Join us as we take a deep dive into the production process of heavy water and discover its many uses.
How is Heavy Water Made?
Heavy water (D2O) can be obtained from natural water or through the use of specialized equipment. The two most common methods for producing heavy water are the Girdler sulfide process and the electrolysis method.
Girdler Sulfide Process
The Girdler sulfide process was invented in the 1930s by American chemists J.K. Girdler and L.E. Hale. This process involves the use of hydrogen sulfide (H2S) to separate heavy water from normal water.
In this process, natural water is first purified to remove any impurities. The purified water is then heated and mixed with hydrogen sulfide gas. The mixture is circulated through a series of towers where heavy water preferentially reacts with H2S to form deuterium sulfide (D2S) and normal water reacts with H2S to form hydrogen sulfide gas. The D2S is then heated to produce heavy water and sulfur.
Electrolysis Method
The electrolysis method involves the use of an electric current to separate heavy water from normal water. This process is based on the fact that heavy water reacts differently to an electric current than normal water.
In the electrolysis method, two electrodes are placed in a container filled with natural water. An electric current is passed through the water, causing the heavy water to accumulate around the negative electrode due to its greater resistance to the current. The heavy water can then be separated and purified using various methods.
