Dupont™ AmberLite™ IRN160 H/OH Ion Exchange Resin
As a premium pre-mixed ion exchange resin tailored for the nuclear power sector, DuPont™ AmberLite™ IRN160 H/OH stands out with nuclear-grade purity, excellent radioactivity removal, and stable long-term performance. It is a stoichiometric 1:1 mixture of AmberLite™ IRN97 H cation resin and IRN78 OH anion resin, specifically designed to meet the strict requirements of nuclear loop water treatment—effectively removing radioactive cations (e.g., ¹³⁷Cs, cobalt isotopes), anionic radioactive materials, and impurities while minimizing equipment maintenance and unscheduled outages. For nuclear power plants, fuel pool management, and rad waste treatment facilities, this resin is the trusted choice for safe, efficient, and compliant water purification.
Why Choose DuPont™ AmberLite™ IRN160 H/OH?
1. Nuclear-Grade Purity, Zero Contamination Risks
• Ultra-Low Impurity Levels: Manufactured via specialized nuclear-grade processes, inorganic impurities (Na, Fe, Co, etc.) are controlled to ≤40 mg/kg (dry basis), and soluble organic compounds are removed to trace levels. This prevents impurity activation in the reactor core, avoiding increased radioactivity and ensuring nuclear system safety.
• High Ionic Purity: As-shipped resin achieves ≥99% H⁺ conversion (cation component) and ≥95% OH⁻ conversion (anion component), with harmful anions like Cl⁻ ≤0.05% and SO₄²⁻ ≤0.1%. No pre-treatment is needed before use, reducing start-up time.
2. Efficient Radioactivity & Impurity Removal
• Dual-Action Purification: Cation resin (IRN97 H) captures radioactive cations (¹³⁷Cs, cobalt isotopes) and heavy metals; anion resin (IRN78 OH) removes anionic radioactive materials and silica. It also efficiently eliminates silver, meeting the strictest water quality standards for nuclear loops.
• High Exchange Capacity: Cation resin offers ≥2.10 eq/L (H⁺ form) capacity, anion resin ≥1.20 eq/L (OH⁻ form)—10-15% higher than standard nuclear resins. Reduces rad waste generation by minimizing resin replacement frequency.
3. Anti-Separation Design, Easy Installation & Transfer
• Minimized Layer Separation: Cation resin (525±50 μm) has a smaller particle size than anion resin (630±50 μm), preventing cation-anion separation during installation and transfer. Eliminates cation layer formation at the service vessel bottom, ensuring uniform purification.
• Fast Change-Out & Rinse: Pre-mixed formula enables quick resin replacement and initial rinse-up. Cuts start-up time by 30% and reduces rinse wastewater volume by 25%, lowering operational costs.
4. Strong Durability, Long Service Life
• Excellent Mechanical Strength: ≥95% whole uncracked beads, with friability resistance (≥400 g/bead for cation, ≥600 g/bead for anion). Withstands high-pressure backwashing and long-term use without breakage or attrition.
• Wide Operating Range: Stable at 5–100°C (41–212°F) and pH 0–14, adaptable to various nuclear water treatment scenarios (e.g., primary coolant blowdown, fuel pool purification).
Uniform pre-mixed spherical beads ensure efficient ion exchange and anti-separation performance
