Which of the following ion of the resin gets exchanged in the anion exchange column?
Which of the following ion get released from the anion exchange column? Explanation: Only OH– ion get released from the anion exchange column.
What is the structure of ion exchange resin?
An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
Which groups are found present in anion exchange resin?
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).
What are the properties of ion exchange resin?
Properties of ion exchange resins
- Swelling. Ion exchange resins are hygroscopic.
- Capacity. Capacity is a number of chemical equivalents of ions that can be taken up by a unit amount of the resin (dry weight/wet weight/wet volume).
- Particle size.
- Stability.
What is Dowex ion exchange resin?
DOW Ion exchange (IX) resins are polymers that are capable of exchanging ions with ions in a solution that is passed through them. DOW’s IX resins come in a variety of chemical compositions, polymer structures, and particle sizes to meet current and developing industry needs and requirements.
What is anion exchange resin chromatography?
Anion exchange chromatography is a form of ion exchange chromatography (IEX), which is used to separate molecules based on their net surface charge. Anion exchange chromatography, more specifically, uses a positively charged ion exchange resin with an affinity for molecules having net negative surface charges.
What is meant by cation exchange resin and anion exchange resin?
There are two general types of ion exchange resins: those that exchange positive ions, called cation exchange resins, and those that exchange negative ions, called anion exchange resins. A cation is an ion with a positive charge.
What type of functional groups are present in cation exchange resins?
Strong cation exchange resins have sulfonic acid (− SO3H) functional groups (e.g., Smith and Chang, 1983). They dissociate to release hydrogen ions, which allows other cations to occupy the ion exchange sites (Harland, 1994).
Which different factors affect the ion exchange equilibria?
The factors that affect separation during ion exchange chromatography include the surface area of the stationary phase (resin bead size); the density of exchange sites on the stationary phase surface (cross-linkage); the flow rate of the mobile phase (resin bead size and column geometry; system pressure in high- …
