Molecular formula :
nature : ion exchange can be regarded as a special kind of solid adsorption process. By solid ion exchange materials with ions of the electrolyte solution between certain ion exchange process, in which the ion exchange materials from the electrolyte solution to draw some kind of cation or anion, and the symbol itself of the charge of the same for another ion exchange as equivalent to extract or remove dissolved some liquid ion purposes. For example, some water through cationic or anionic ion exchanger was replaced by some other ion process. This exchange reaction under certain conditions are reversible. Mainly for water softening, or desalination; Solution refining and bleaching; Uranium and the extraction of rare metals from industrial wastewater recycling precious metals.
