Levextrel Resin
CL-C272
High Selectivity (Calcium/Magnesium/Heavy Metals): Affinity to divalent cations follows the order: Ca²⁺ > Mg²⁺ > Cu²⁺ > Ni²⁺ > Co²⁺ > Zn²⁺ > Fe²⁺ > Sb³⁺ > Na⁺, ensuring efficient removal of calcium, magnesium, and heavy metals even in high-salt/high-hardness environments.
Product Details
Core Characteristics
• High Selectivity (Calcium/Magnesium/Heavy Metals): Affinity to divalent cations follows the order: Ca²⁺ > Mg²⁺ > Cu²⁺ > Ni²⁺ > Co²⁺ > Zn²⁺ > Fe²⁺ > Sb³⁺ > Na⁺, ensuring efficient removal of calcium, magnesium, and heavy metals even in high-salt/high-hardness environments.
• Complexing Resistance and Compatibility: Adsorbs heavy metals in the presence of complexing agents such as ammonia, EDTA, and citric acid, suitable for complex industrial wastewater from electroplating, mining, and other industries.
• Excellent Kinetics and Stability: Macroporous structure, resulting in a fast exchange rate.
• Wear-resistant and resistant to osmotic shock, with a low breakage rate over long-term cycles.
• Wide pH Range: Operating pH 1–10, covering acidic to alkaline wastewater scenarios, with strong resistance to organic pollution.
Typical Applications
• Chlor-alkali industrial brine purification: Removes Ca²⁺, Mg²⁺, Sr²⁺, and Ba²⁺ from brine, protecting electrolytic cell membranes and extending their service life.
• Electroplating/PCB wastewater: Removes Cu, Ni, Pb, Cd, Zn, and Sb, achieving effluent quality down to ppb levels, and recovers valuable metals.
• Hydrometallurgy: Removes impurities from sulfate/chloride electrolytes, extracts nickel and cobalt, separates rare earth elements, and recovers antimony and bismuth.
• Groundwater/drinking water: Removes toxic heavy metals such as arsenic, lead, cadmium, chromium, and antimony, meeting drinking water standards.
• Industrial surface treatment: Recovers Ni, Co, and Cu from metal rinsing water; selectively removes heavy metals in high-calcium environments.
