Description

Strong Acid Cation Exchange Polymer Hydrogen Ion Form is a high-capacity, macroporous resin designed for the selective removal of cations from aqueous and non-aqueous solutions. This product is essential for processes requiring high-purity water, metal recovery, and catalysis, offering superior chemical stability and regeneration efficiency. It is a critical component for industries including pharmaceuticals, power generation, hydrometallurgy, and chemical synthesis, where reliable ion separation is paramount.

Application

• Ultrapure Water Production: Demineralization and polishing in power plant boilers, semiconductor manufacturing, and laboratory water purification systems.
• Chemical Processing & Catalysis: Serving as an acid catalyst in esterification, alkylation, and hydrolysis reactions, offering a reusable alternative to liquid mineral acids.
• Hydrometallurgy & Metal Recovery: Selective extraction and concentration of valuable or toxic metal cations (e.g., copper, nickel, zinc) from process streams and waste effluents.
• Pharmaceutical Purification: Separation and purification of active pharmaceutical ingredients (APIs), antibiotics, and amino acids through ion exchange chromatography.
• Sugar & Sweetener Refining: Decolorization, deashing, and pH adjustment in the processing of sugar syrups and high-fructose corn syrup.
• Food & Beverage Processing: Water softening, dealkalization, and stabilization of products like fruit juices, wines, and dairy ingredients.
• Environmental Remediation: Treatment of industrial wastewater and leachate to remove heavy metals and ammonium ions for regulatory compliance.
• Nuclear Industry

Quality Control

Our Strong Acid Cation Exchange Resin is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key performance indicators including total exchange capacity, moisture holding capacity, particle size distribution, and uniformity coefficient to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications are available upon request. Our production and quality processes are designed to support compliance with relevant standards for water treatment and chemical processing applications.

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 material is hygroscopic (moisture-sensitive); the original container must be kept sealed to prevent moisture uptake, which can affect performance. Keep away from strong oxidizing agents and strong bases.
