Sigma-Aldrich Amberlite™ IR120 Na+ form, sodium form, 15-50 mesh

Sigma-Aldrich Amberlite™ IR120 (Na⁺) is a high-capacity, strongly acidic cation exchange resin in sodium (Na⁺) form, designed for water softening, toxic metal recovery, and chromatographic separations. This polystyrene-divinylbenzene gel-type resin is cross-linked at 8%, providing excellent mechanical and chemical stability for a wide range of industrial, laboratory, and environmental applications.

Amberlite™ IR120 Na⁺ is highly effective in removing hardness ions such as calcium (Ca²⁺) and magnesium (Mg²⁺) from water, as well as in toxic metal recovery, column chromatography, and ion-exchange separation techniques. It is commonly used in water deionization, chemical purification, and laboratory ion exchange chromatography applications.
