Demystifying Ion Exchange Resins: Understanding Anion and Cation Exchange

Ion exchange resins can be broadly categorized into two types: anion exchange resins and cation exchange resins. The key difference between these resins lies in the type of ions they attract and exchange.

Anion Exchange Resins: Anion exchange resins are designed to attract and exchange negatively charged ions, known as anions. These resins have functional groups, such as quaternary ammonium, that carry a positive charge. When an anion-containing solution passes through the resin bed, the anion exchange resin attracts and binds the anions, effectively removing them from the solution...
