Ion exchange properties are based on the isoelectric point (pI) of a protein. WebThere 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. Common cations include Ca +2, Mg +2, Fe +2, and H +1. A cation resin is one that exchanges positive ions.

Web22 apr. 2024 · Many studies on ion exchange are conducted in five main stages. The first stage in the IEC is the equilibrium where the ion-exchanger is brought into a starting state. The second stage in the IEC is the application of samples and adsorption, in which solute analytes moving the required charge displace counter-ions and bind the gel in reverse. WebThe Ion Exchange Demineralisation Process (Strongly functional Resins) • Strong acid cation resins (SAC) exchange H + ions with cation portion of TDS and are regenerated by dilute acid solution (H +) – Water becomes decationised resulting in a solution of weak and strong acids • Strong base anion resins (SBA) exchange OH-ions with anion WebIon Exchange Methodology In order for electrostatic retention to occur, both analyte and sorbent functional groups must be in their ionizedIon Exchange Methodology form.
