Performance
Characteristic Reaction
R-CH₂-NH-CH₂-PO₃Na₂ + M²⁺ → R-CH₂-NH-CH₂-PO₃M + 2 Na⁺
Relative Affinity
The relative affinity of this resin for the various cations decreases in the order: Pb²⁺ > Cu²⁺ > Zn²⁺ > Mg²⁺ > Ca²⁺ > Cd²⁺ > Ni²⁺ > Co²⁺ > Sr²⁺ > Ba²⁺
Operating pH Range
The resin can operate in a neutral, acidic, or alkaline medium. Recommended minimum pH values are:
- Cations: Cu²⁺, Zn²⁺, Cd²⁺, Mg²⁺, Pb²⁺, Ca²⁺, Ni²⁺, Co²⁺
- Minimum pH: 2, 2.5, 3, 4.5 (corresponding to the listed cations)
Applications
- Brine Purification: Removal of Ca, Mg, and other metals from concentrated brine (e.g., chlor-alkali electrolysis).
- Zinc Separation: Separation of zinc from various media.
- Lead Separation: Separation of lead from industrial effluents.
Hydraulic Characteristics
Refer to the original datasheet for figures illustrating bed expansion as a function of backwash flow rate and temperature, and pressure drop in brine as a function of linear velocity and temperature.
