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) . A cation exchange resin with a negatively charged matrix and exchangeable positive ions (cations) is shown in.
Table I: Classification and Properties of Numerous Ion Exchange Resins offered by Aldrich. Related Polymeric Adsorbents, Aldrich Logo . Ion exchange resins are polymers that are capable of exchanging particular ions within the. Use this strongly basic analytical grade anion exchange resin for high-resolution, low-molecular-weight separations.

The dark lines represent the polymeric skeleton of the resin bead: it is porous and contains water. Ions with a positive charge are called “Cations” and ions with a negative charge are called “Anions”. Ion exchange resins are used to exchange non-‐desirable . Anion exchange chromatography is a form of ion exchange chromatography where a negatively charged biomolecule binds to a positively charged resin.
Ion exchange for industrial water treatment uses both cation exchange resins and anion exchange resins to facilitate deionization and demineralization. In a cation-exchange resin all the sites are negatively charge so that only positive ions can be separated; an anion-exchange resin has positively charged sites . Ion-exchange resin, any of a wide variety of organic compounds synthetically polymerized and containing positively or negatively charged sites . In a cation-exchange resin all the sites are negatively charge so that only .
Weiter zu Resin fouling and degradation – Organically bound iron passes through a cation unit and fouls the anion resin. QIAGEN-tips contain a unique, patented anion-exchange resin which eliminates the need for expensive equipment and reagents such as ultracentrifuges, . An ion-exchange resin or ion-exchange polymer is an insoluble matrix normally in the form of small beads. Ion exchange (IX) resin technology has been used extensively as a practical and effective form of water treatment for many years.
Ion exchange resins are classified as cation exchangers, which have positively charged mobile ions available for exchange, and anion . When it comes to resin selection the magic number is:. It is the H+ ion connected to the COO- which exchanges with the cations associated with the temporary . DOW Ion Exchange Resins – Type and Type Strong Base Anion Resins Differences. Spectrum Ion Exchange Resins are ideal for preparative scale ion exchange chromatography. Ion-exchange selectivity of anion exchange resin modified with polystyrenesulfonic acid. A physical property of the ion exchange resins that changes with changes in crosslinkage is the moisture content of the resin.
Ion exchange resins are particularly well suited for the removal of ionic impurities for several reasons: the resins have high capacities for ions that are found in . Eichrom supplies an expanding range of cation and anion exchange resins, purified for the needs of analytical applications. Ion exchange resin properties: capacity, moisture, particle size, ionic form, swelling, density.
