Amberlite IRC86RF

Summary

Product identification

• Product Name: AMBERLITE™ IRC86RF
• Type: Industrial Grade Weak Acid Exchanger
• Description: Gel type, high capacity weak acid cation exchange resin containing carboxylic acid groups. Principal application is dealkalization of industrial waters. Removes hardness associated with alkalinity when in the hydrogen cycle. Particle size is designed for packed bed and floating bed systems. Reduces acid regenerant consumption when used with a strong acid cation exchanger in demineralizer systems.

* 1 BV (Bed Volume) = 1 m³ solution per m³ resin

Performance

Operating Capacity

Operating capacity is a function of analysis, temperature, and service flow rate. Engineering data sheet (EDS 0235 A) provides information for capacity calculation.

Regeneration

Readily regenerated with slightly over stoichiometric amounts of strong acids. If sulfuric acid is used, a low concentration (≤ 0.7 %) is advised to avoid calcium sulfate precipitation.

Limits of Use

• Not recommended for applications involving complete conversion between H⁺ and Na⁺ or NH₄⁺ forms due to high swelling.
• Suitable for industrial uses.
• For pharmaceutical, food processing, or potable water applications, consult Rohm and Haas for resin choice and operating conditions.

Hydraulic Characteristics

Bed expansion and pressure drop data are provided in graphical form (Figures 1 and 2) as a function of backwash/service flow rate and water temperature. Hydraulic curves are for H⁺ form resin.
