Abstract:It was discovered that the solvent composition, the concentration of phosphoric acid, and the presence of iron, aluminium, calcium, magnesium and silicon in aqueous phase affeet extracting process. The most suitable conditions for the separation are ascertained. The mechanism of the extraction process was preliminarily studied.
Keywords:fluoride  extraction  separation  phosphoric acid  removal of fluoride  solvent extraction  purification of phosphoric acid
