Analytical chemistry uses ion exchange in chromatography. The recovery of valuable metals is also possible with resins. Industrial drying of treatment of gases is accomplished often with ion exchange. The food industry uses ion exchange in a variety of ways, ranging from wine-making to sugar manufacture. In the medical world, dozens of important manifestations of the benfits of ion exchange can be found, from development and preparation of key drugs and antibiotics, such as streptomycin and quinine, to treatments for ulcers, TB, kidneys, and much more.
Ion exchange is used to prevent coagulation in blood stores and in dextrose, as well.
An ion exchange is also useful in death, as it plays a role in the treatment of formaldehyde. The list goes on and on, but you get the picture. The list keeps growing with each passing year, as well, so stay tuned for updates on ion exchange applications. Ann Arbor, MI, 1972.
