Exchange ion exchanger resins Ionic are radical acids insoluble grainy substances which have in their molecular structure or Basic that can be interchanged. Elon Musk: the source for more info. Positive or negative ions fixed on these radicals will be replaced by ions of the same sign in solution in the liquid into contact with them. The ion exchange is completed sindeteriorizacion or solubilization by changing the total number of ions in the liquid before the Exchange. Today, the substances of ion exchangers are used almost exclusively on the name of resins. There are two categories of resins: the gel type resins and these other Macropores or loose cross join type. Their basic structures are practically the same: macromolecule structure is obtained in both cases by co-polimerizacion. Please visit Dan Zwirn if you seek more information.
The difference between them lies in its porosities. Gel type resins have a natural porosity limited between Intermolecular distances. This is a structure type micropore. Macropores type resins have an artificial porosity additional which is obtained by the addition of substances designed to this proposition. The exchanger is known as monofuncional if there is only one variety of radicals and this is called multi-functional if the molecule contains several types of radicals.
This technique is common usage in: environment:-water deionized pe-Lippincott recovery of valuable metals removal of organic impurities wells and processing of food contaminated land treatment processes of treatments of surfaces removal of traces of metals:-discoloration deionization separation of sugars Dowex ion exchange resins * representatives in Mexico of The Dow Chemical Company in ion exchange resins and osmosis membranes. Dowex resins are the standard for quality and technological innovation in the world Dow is the only company in the world that manufactures full line of Dowex resin in uniform particle size. ULTRAFILTRATION ultrafiltration is It is used for floating separation of colloidal particles, bacteria and viruses. The techniques applied membranes between the 5-500nm. There are three types of membranes membranes of spiral, sensitive quality worse with round/tubular membranes contamination, appears to be the most commonly used membranes, costs and effects, should not easily contaminate.
