Mixed-Bed Ion Exchange Resin, Hydrogen and Hydroxide Form

Description

Mixed-Bed Ion Exchange Resin, Hydrogen and Hydroxide Form, is a homogeneous mixture of strong acid cation (SAC) resin in the H⁺ form and strong base anion (SBA) resin in the OH⁻ form. This combination provides simultaneous removal of cations and anions, delivering exceptionally high-quality deionized water in a single step. The cation component is typically a sulfonated polystyrene–divinylbenzene copolymer, while the anion component is a quaternary ammonium functionalized polystyrene–divinylbenzene copolymer. Together, these resins produce water with very low conductivity and silica content, making them ideal for ultrapure water applications.

Applications

• Ultrapure water production for power plants, electronics, and semiconductor industries

• Final polishing in deionization systems

• Laboratory-grade ultrapure water systems

• Condensate polishing units in power generation

• Pharmaceutical and biotechnology process water

• High-purity water for food and beverage production

• Polishing after reverse osmosis or demineralization units

Key Features

• Balanced mixture of cation (H⁺) and anion (OH⁻) resins

• Delivers ultrapure water with very low conductivity

• Effective silica and CO₂ removal

• High chemical and thermal stability
