D111 Macroporous Weak Acid Cation Exchange Resin
About this Product:
The D111 is a macroporous weak acid cation exchange resin based on an acrylic acid-divinylbenzene copolymer with carboxylic acid functional groups.
This resin delivers outstanding performance, highlighted by its large exchange capacity, rapid exchange kinetics, and minimal volume change. Designed for robustness, the D111 boasts superior physical strength and excellent chemical stability, providing strong resistance to both contamination and oxidation.
Key Applications:
The D111 resin is a versatile and effective solution for a wide range of industrial applications, including:
Food & Beverage: Instrumental in the decolorization and removal of ash in the sugar industry, improving product purity and quality.
Pharmaceuticals & Biotechnology: Essential for the extraction of antibiotics like streptomycin, gentamicin, neomycin, and for the separation and purification of various biochemical products, including lysozyme.
Water Treatment: Primarily used for the softening and demineralization of industrial-use water.
Environmental Remediation: Effective in the removal of heavy metals from wastewater.
