NIP Anion Exchange Resins
NIP Anion Resin is a synthetic ion exchange resin designed to remove anions such as chloride, sulfhate, nitrate, fluoride, bicarbonate, and silica from water. It works on the principle of ion exchange, where negatively charged ions in the water are exchanged with hydroxide (OH⁻) ions held by the resin. It is commonly used in demineralization, deionization, and water softening systems, usually paired with cation exchange resins to produce high-purity water..
Key Features/Properties
- Type: Strong base anion exchange resin (quaternary ammonium functional group).
- Appearance: Usually light yellow to amber-coloured spherical beads.
- Functional group: –N⁺(CH₃)₃ (quaternary ammonium).
- Ionic form: Supplied in chloride (Cl⁻) or hydroxide (OH⁻) form.
- Exchange capacity: High ion exchange capacity for various anions.
- Applications:
- Water deionization/demineralization
- Power plants and boiler feedwater treatment
- Pharmaceutical and food-grade water purification
- Removal of nitrates, sulphates, and silice
