What is strong cation exchange resin?
What is strong cation exchange resin?
The strongly acidic cation exchange resins are bead-like products which have a sulfonic acid group in the cross-linked styrene frame. They can be used across the full pH range (0-14), and are relatively stable to temperature, even withstanding high temperatures of 100-120℃.
Which is example of strong anion exchanger?
Strong anion exchangers are able to maintain their positive charges across a variable pH range while weak anion exchangers tend to lose their charge as the pH increases. Examples of anion exchangers include the strong anion exchanger Q (quaternary resin), and the weak anion exchanger DEAE (diethylaminoethane).
Which is an example of cation exchange resin?
The most commonly available cation exchange resin is sodium polystyrene sulfonate (Kayexalate). In the gut, sodium polystyrene sulfonate absorbs potassium and releases sodium.
What resin is used in cation exchange chromatography?
Anion resins and cation resins are the two most common resins used in the ion-exchange process. While anion resins attract negatively charged ions, cation resins attract positively charged ions.
What are strong and weak ion-exchange resins?
The terms “strong” and “weak” refer to the acid/base properties of the functional group. If the ligand is derived from a strong acid or a strong base it is referred to as a strong ion exchange resin. If the ligand is derived from a weak acid or a weak base it is referred to as a weak ion exchange resin.
What is strong base anion?
Strong base anion unit is a vessel in which an ion exchange process takes place. OH¯ ions replace the anions present in TDS to produce demineralized water. The anions present in the water i.e. Cl, SO4, HCO3 and silica etc.
What are strong and weak ion exchange resins?
Which is an example of weak anion exchanger?
Weak anion exchangers (DEAE- and CM-resins) have often been used for purification of membrane proteins, but strong ion exchangers designed for use in FPLC, such as Mono Q and Mono S (Pharmacia), now are commonly applied.
What are the 4 types of ion exchangers?
Ion exchangers can be ion exchange resins (functionalized porous or gel polymer), zeolites, montmorillonite, clay, or even soil humus.
What is a weak cation exchange resin?
The weakly acidic cation exchange resins have the carboxylic acid group (-COOH) as the exchange group. There are two kinds — a methacrylic acid type and an acrylic acid type. The acrylic acid weakly acidic cation exchange resin is used for processing water with high carbonate hardness.
