How do you manufacture ion exchange resin?
The manufacture of ion exchange resins involves the preparation of a cross-linked bead copolymer followed by sulfonation in the case of strong acid cation resins, or chloromethylation and the amination of the copolymer for anion resins.
How many types of ion exchange resin are there?
two
Ion exchange resins consists of two main types, i.e., cation exchange resins, that exchange positively charged ions, such as sodium, for calcium, and anion exchange resins, that exchange negatively charged ions, such as chloride, for arsenic.
Where is Purolite resin made?
Purolite has manufacturing facilities in the United States, China, Romania and the United Kingdom.
What is XAD 7 resin?
AmberLite™ XAD™7HP Polymeric Adsorbent is a macroporous resin combining high surface area with an aliphatic adsorbent resin structure. Due to its aliphatic nature, AmberLite™ XAD™7HP can adsorb non-polar compounds from aqueous systems and can also adsorb polar compounds from non-polar solvents.
What is macroporous resin?
Macroporous resin is an organic adsorbent composed of high polymers and was developed in the 1960s. It has an internal three-dimensional stereoscopic pore structure, and good adsorption properties due to the numerous reticular cavities with a large specific surface area [3-4].
Who makes Purolite resin?
Core Technologies As the global leader in resin technology, we develop and manufacture small beads that are used in the most regulated industries in the world to separate, remove or recover very specific elements and compounds.
Who owned Purolite?
firm for $3.7B deal. Purolite is a family-owned company founded in 1981 by brothers Steve and Don Brodie in Don’s basement. Both brothers remain active in the company.
What is XAD 2 resin?
Amberlite XAD-2, a hydrophobic copolymer of styrene-divinylbenzene resin, requires longer purification process and is used as a sorbent. Amberlite XAD-2 resin depending upon the aromaticity and size of the hydrophobic groups sorbs organic compounds through low-energy physical interactions.
What Amberlyst 15?
Amberlyst 15 is a heat sensitive macro-porous sulfonic ion exchange acid resin which could be used as a catalyst.
What is macroporous adsorption resin?
What are ion-exchange resins made of?
Ion-exchange resins are generally made from methacrylic acid, sulfonated styrene, and divinylbenzene (DVB).
What is exchange capacity of resin?
One important characteristic of ion exchange resin is its capacity, expressed in terms of milliequivalents of exchangeable ion per gram of resin. Exchange capacity can be measured by exchanging sodium ion (Na+) for. hydrogen form (H+ initially attached to the resin).
