Ion Exchangers
Ion exchangers are materials that can selectively remove or exchange ions from a solution. In the context of space and astronautical engineering, ion exchangers are used in various applications such as water purification, air revitalization, and waste management. In spacecraft, ion exchangers are used to remove impurities from the water supply and to remove carbon dioxide from the air. They are also used in the treatment of urine and other waste products. Ion exchangers can be made from a variety of materials, including natural and synthetic resins, zeolites, and activated carbon. The choice of material depends on the specific application and the types of ions that need to be removed or exchanged.
