Description

Lewatit TP-208 is a high-performance, macroporous, weakly acidic cation exchange resin designed for specialized industrial separation and purification processes. Its core value lies in its exceptional selectivity for specific metal ions, enabling efficient recovery and purification in demanding chemical environments. This product is essential for industries requiring precise metal separation, such as hydrometallurgy, wastewater treatment for heavy metal removal, and the catalysis sector for precious metal recovery. The compound is also known by the CAS registry number 126602-47-9.

Application

• Hydrometallurgy: Selective recovery of valuable metals like copper, nickel, and cobalt from leach solutions.
• Wastewater Treatment: Removal and concentration of heavy metal ions (e.g., lead, cadmium, zinc) from industrial effluents.
• Catalyst Recovery: Separation and purification of precious metal catalysts, such as palladium and platinum, from process streams.
• Chemical Purification: Scavenging of trace metal impurities from high-purity chemical and pharmaceutical intermediates.
• Analytical Chemistry: Used as a stationary phase or sorbent for the preconcentration and separation of metal ions prior to analysis.
• Nuclear Industry: Potential application in the separation of specific radionuclides from nuclear waste solutions.

Quality Control

Our Lewatit TP-208 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as total exchange capacity, moisture holding capacity, particle size distribution, and chemical stability are rigorously tested. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to guarantee compliance with your technical requirements.

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). Keep away from strong oxidizing agents and incompatible materials. The resin is supplied in a moist state and should not be allowed to dry out, as this may affect its performance characteristics.
