Anion resin (CleanTech Engineering) is a type of ion exchange resin that is specifically designed to remove negatively charged ions (anions) from liquids, typically water. It’s commonly used in water purification and treatment processes.
🔹 What is Anion Resin Made Of?
Anion resins are usually made of synthetic organic polymers, such as polystyrene, which have functional groups attached that attract and hold negatively charged ions. These groups can include:
- Quaternary ammonium groups (strong base anion resin)
- Amine groups (weak base anion resin)
🔹 Types of Anion Resins
- Strong Base Anion (SBA) Resin
- Removes all types of anions including chloride, nitrate, sulfate, and even weak acids like silicic acid and carbon dioxide.
- Works across a broad pH range.
- Example: Used in demineralization of water.
- Weak Base Anion (WBA) Resin
- Removes strong acid anions (like chloride, sulfate) but not weak acids.
- Typically used as a pre-treatment resin or for organic removal.
🔹 Applications
- Water deionization (with cation resin)
- Demineralization for industrial boilers
- Removal of nitrates, arsenic, or chromates in drinking water
- Mixed bed systems (combined with cation resin for ultrapure water)
🔹 Example Reactions
For a strong base anion resin in the hydroxide form:
R–N(CH₃)₃⁺ OH⁻ + Cl⁻ → R–N(CH₃)₃⁺ Cl⁻ + OH⁻
The resin exchanges the hydroxide ion (OH⁻) for chloride (Cl⁻).
