Di (2-ethylhexyl) Phosphate (P204)

Application: This product is an acidic phosphorus extractant, mainly used for extraction and separation of rare metals and rare earths, and can also be used in medicine, printing and dyeing, petrochemical wastewater treatment and other industries.

Packaging: 200 kg/plastic barrel; 1000 L/IBC ton barrel.

Storage and transportation: Handled with care during transportation to prevent impact. Stored in a cool, ventilated and dry warehouse, ensuring fire prevention and rain proof.

Complex Formation: P204 acts as a complexing agent, forming coordination compounds with metal ions present in an aqueous solution. When P204 is dissolved in an organic solvent, it creates an interface between the aqueous and organic phases.

Selective Extraction: P204 selectively extracts specific metal ions from the aqueous solution into the organic phase. The metal ions form complexes with P204, which have higher solubility in the organic solvent compared to the aqueous phase.

Phase Separation: After the extraction, the organic phase containing the metal-P204 complexes is separated from the aqueous phase. This separation is facilitated by differences in density or the use of specific techniques such as centrifugation or settling.

Phase Separation: The metal-P204 complexes in the organic phase can be further processed to recover the desired metal. Stripping agents or solutions are used to break the complexes, releasing the metal ions into a new aqueous solution or suitable medium.

Purification and Recycling: The metal ions can undergo subsequent purification steps to obtain a high-purity metal product. Meanwhile, the organic phase, containing P204, can be recycled by removing impurities and reusing it in the extraction process.
