WebApr 10, 2024 · An ion exchange system for nitrate reduction works similarly, exchanging chloride ions with nitrate ions on a charged resin bed. When the chloride is used up and the resin is saturated with nitrates, the system regenerates, recharging the resin with a sodium chloride solution. Anion-exchange chromatography is a process that separates substances based on their charges using an ion-exchange resin containing positively charged groups, such as diethyl-aminoethyl groups (DEAE). In solution, the resin is coated with positively charged counter-ions (cations). Anion exchange resins will bind to negatively charged molecules, displacing the counter-ion. Anion exchange chromatography is commonly used to purify proteins, amino acids, sugars/carbo… WebThe weak anion exchange resin is inert to a wide variety of solvents, stable in the pH range 0 to 14, and water-wettable.
