Description

Ammonium Bis(2-Ethylhexyl) Phosphate is an organophosphorus compound widely utilized as a versatile extractant and phase transfer catalyst. Its primary commercial value lies in its exceptional ability to selectively separate and purify valuable metal ions from complex aqueous solutions. This makes it a critical component for companies in the hydrometallurgy, rare earth element processing, and nuclear fuel reprocessing industries seeking efficient and reliable separation technologies.

Application

• Solvent Extraction in Hydrometallurgy: Key extractant for the recovery and purification of metals like copper, nickel, cobalt, and zinc from leach solutions.
• Rare Earth Element (REE) Separation: Employed in liquid-liquid extraction processes to separate individual lanthanides due to its selective complexation properties.
• Nuclear Fuel Cycle Processing: Used in the PUREX and related processes for the extraction and separation of uranium and plutonium from spent nuclear fuel.
• Catalyst and Additive: Serves as a phase transfer catalyst in organic synthesis and as an additive in lubricants and corrosion inhibitors.
• Analytical Chemistry: Utilized as a chelating agent for the pre-concentration and analysis of trace metal ions.
• Wastewater Treatment: Applied in the selective removal of heavy metal contaminants from industrial effluents.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance. Keep away from strong bases and incompatible materials.
