Features Of Lanxes-s LEWATIT MDS 1268 K 290 Ion Exchange Resin

  1. Highly selective for divalent cations including Ca²⁺, Mg²⁺, and heavy metals in complex aqueous matrices.

  2. Optimized macroporous structure providing excellent kinetic performance and resistance to fouling from organic matter.

  3. Stable under repeated regeneration cycles with strong acid (e.g., HCl or H₂SO₄), ensuring long service life.

  4. Low osmotic swelling behavior, maintaining consistent bed volume and hydraulic performance across pH 1–14.

  5. Sulfonic acid functional groups grafted onto a styrene-divinylbenzene copolymer backbone for robust chemical and thermal stability.

Typical Applications Of Lanxes-s LEWATIT MDS 1268 K 290 Ion Exchange Resin

  1. Pre-treatment polishing in high-purity water systems for pharmaceutical and biotechnology manufacturing.

  2. Removal of hardness and trace metal ions from industrial process streams in power plant boiler feedwater circuits.

  3. Recovery and concentration of valuable metal ions (e.g., Ni²⁺, Co²⁺, Cu²⁺) in hydrometallurgical leach solutions.

  4. Decolorization and impurity removal in sugar refining and organic acid purification processes.

  5. Effluent treatment for compliance with stringent discharge limits on heavy metals in electroplating and metal finishing wastewater.
