Which groups are found present in anion exchange resin?

Which groups are found present in anion exchange resin?

15.7. The functional groups are sulfonic (–SO3H), carboxylic (–COOH), or phosphonic (–PO32 −) acids for resins capable of exchanging cations, whereas anion exchange resins possess basic functional groups, such as quaternary ammonium or ammine groups (Korkisch, 1989).

Which resin is used in ion exchange process?

Three ion-exchange resins, sodium polystyrene sulfonate, colestipol, and cholestyramine, are used as active ingredients. Sodium polystyrene sulfonate is a strongly acidic ion-exchange resin and is used to treat hyperkalemia. Colestipol is a weakly basic ion-exchange resin and is used to treat hypercholesterolemia.

How does the ion exchange resin work?

The ion exchange chemical process works by removing dissolved ionic contaminants from the water. These ions are swapped for better ones that won’t degrade the quality of your water. Water softeners are very similar to ion exchange systems since both systems can remove magnesium and calcium ions from the water.

What are the different types of ion exchangers?

Ion exchangers are either (i) cation exchangers, which exchange positively charged ions—cations, or (ii) anion exchangers which exchange negatively charged ions—anions….Ion Exchanger

  • pH.

What is ion exchange resin and how does it work?

Ion Exchange Resin is comprised of a bed of cation and anion resins which are negatively and positively charged respectively to purify water by removing ions or salts. To accomplish this, an exchange occurs by trapping ions in the resin beads and releasing other ions.

What is an ion exchange resin used for?

Ion-exchange resin beads. Ion-exchange resins are widely used in different separation, purification, and decontamination processes. The most common examples are water softening and water purification. In many cases ion-exchange resins were introduced in such processes as a more flexible alternative to the use of natural or artificial zeolites. Nov 21 2019

What is an ionic exchange resin?

An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange.

What is the difference between cation and anion exchange resins?

How cation and anion exchange resins are different. The main difference between cation and anion resins is that one is positively charged (cation) and the other is negatively charged (anion). This makes them useful in removing different types of contaminants (which will also vary depending on their size and chemical composition).
