Description

Duolite(R) Es 468 1.8 Meq/Ml is a high-capacity, strongly basic anion exchange resin supplied in the chloride form. This product is engineered for superior performance in demanding industrial separation and purification processes, offering consistent quality and reliable ion exchange capacity. It is essential for applications requiring the removal or recovery of anions from aqueous and non-aqueous streams across various sectors.

Application

• Water Treatment & Demineralization: For the removal of anions such as nitrate, sulfate, and chloride in the production of high-purity water for power generation, pharmaceuticals, and electronics.
• Chemical Processing & Catalysis: Used as a catalyst or catalyst support in organic synthesis reactions, including esterification and transesterification.
• Sugar & Sweetener Refining: For decolorization and demineralization in the purification of sugar syrups, high-fructose corn syrup (HFCS), and other sweeteners.
• Pharmaceutical Purification: In the isolation and purification of antibiotics, vitamins, and other active pharmaceutical ingredients (APIs) through chromatographic separation.
• Metal Recovery & Hydrometallurgy: For the selective recovery of precious metals like gold and platinum, or the removal of heavy metal complexes from mining and electroplating effluents.
• Food & Beverage Processing: Employed in the deacidification of fruit juices, stabilization of wine, and removal of off-flavors or colors.
• Nuclear Industry: For the treatment of low-level radioactive wastewater by removing radioactive anionic species.

Quality Control

Our Duolite(R) Es 468 resin is manufactured under a strict quality management system. Each batch is tested to ensure it meets critical parameters such as ion exchange capacity, moisture content, particle size distribution, and uniformity coefficient. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the original container sealed to prevent moisture uptake and degradation of performance. Do not store near strong acids or oxidizing agents.
