Application Information

The resin exhibits selectivity for metal ions in the following general order: Fe³⁺ > Hg²⁺ > Cu²⁺ > Pb²⁺ > Ni²⁺ > Zn²⁺ > Cd²⁺ > Co²⁺ > Fe²⁺ > Mn²⁺ > Ca²⁺ >> Na⁺

The affinity for H⁺ at pH 4 is situated between Cu²⁺ and Pb²⁺. For metals with selectivities less than Cu²⁺, the resin should be in the salt form (e.g., Na⁺ form) to minimize metal leakage. At pH 2, the resin will be extensively in the H⁺ form and will efficiently remove Fe³⁺, Hg²⁺, and Cu²⁺.

Selectivity at various pH conditions is presented in tables within the original document. Minimum pH values are recommended for various cations to ensure effective operation.
