D201 Macroporous Styrene Series Strongly Alkaline Anion Exchange Resin
About this Product:
This anion exchange resin is a high-performance alternative to the 201×7 Strong-Base Type I (Gel) Anion Exchange Resin, providing superior physical and chemical stability. Its macroporous structure offers enhanced resistance to permeation, abrasion, and contamination.
This robust design allows it to effectively exchange large-sized ions and molecules, making it particularly well-suited for use in non-aqueous mediums—a capability not typically found in conventional gel resins.
Application
This macroporous resin is a versatile solution for a wide range of industrial applications, including:
Specialty Extractions: Employed for the adsorption and extraction of vanadium pentoxide, a critical process in hydrometallurgy.
Water Purification: Essential for the manufacture and purification of both pure water and high-purity water.
Food & Beverage: Used for the decolorization of sugar and fermentation solutions, ensuring product quality.
Environmental Remediation: Effective in wastewater treatment and the recycling of heavy metals.
