Description

Lewatit TP-207 is a specialized chelating ion exchange resin designed for the selective removal of heavy metal ions from aqueous solutions. This product is critical for industries requiring high-purity process streams and effective wastewater treatment to meet stringent environmental regulations. Key sectors that rely on this technology include hydrometallurgy for metal recovery, power generation for condensate polishing, and the production of high-purity chemicals and electronics.

Application

• Hydrometallurgical Metal Recovery: Selective extraction and purification of valuable metals like copper, nickel, and cobalt from leach solutions.
• Industrial Wastewater Treatment: Removal of toxic heavy metals (e.g., lead, cadmium, mercury) to comply with discharge limits.
• Power Plant Water Systems: Polishing of condensate and feedwater to protect turbines from metal ion contamination.
• Catalyst Protection: Guard bed application to remove trace metal poisons from feedstocks in chemical and petrochemical processes.
• Electronics & Semiconductor Manufacturing: Production of ultra-pure water by removing ionic impurities.
• Pharmaceutical & Fine Chemical Synthesis: Purification of intermediates and final products by scavenging metal catalysts and impurities.

Quality Control

Every batch of Lewatit TP-207 is manufactured and tested under a strict quality management system to ensure consistent performance and reliability. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing key parameters such as total capacity, moisture content, bead size distribution, and heavy metal selectivity are available upon request.

Storage

Preserve in a tightly closed container, protected from light. This resin is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C). Keep the original container sealed to prevent moisture uptake and contamination. Store away from strong oxidizing or reducing agents.
