Suqing D318 from Suqing's acrylic-based macroporous anion exchange resin range is a high-performance macroporous anion exchange resin developed for food and pharmaceutical purification and special water treatment. With free amine ionic form, it appears as milky white to pale yellow spherical particles, featuring ultra-high exchange capacity and excellent mechanical strength
Ultra-high exchange capacity - Excellent ion exchange efficiency and large adsorption capacity, capable of treating high-concentration anion-containing media, reducing treatment costs.
Outstanding mechanical performance - Post-grinding sphericity ≥90%, high mechanical strength, strong resistance to abrasion and osmotic pressure shock, long service life.
Precise selective adsorption - Outstanding selectivity for anions such as SO₄²¯, Cl⁻ and NO₃⁻, high adsorption accuracy, ensuring purification effect.
Food industry purification: Adsorption and purification in citric acid and vitamin C production processes, improving product purity and quality.
Pharmaceutical industry refinement: Removal of anionic impurities in pharmaceutical intermediates and drug production, ensuring drugs meet pharmacopoeia standards.
Industrial wastewater treatment: Treatment of SO₄²¯ and Cl⁻ containing wastewater in smelting, chemical and other industries to achieve compliance with discharge standards.
