Abstract

L'invention concerne un procédé de purification d'un acide phosphorique de voie humide. L'acide brut de voie humide extrait au solvant et régénéré à l'aide d'eau selon le brevet principal est ensuite soumis à un traitement à l'aide de vapeur d'eau ou de gaz chaud ce par quoi l'on obtient une solution concentrée d'acide phosphorique d'un rapport pondéral F/P2 O 5 inférieur à 10 ppm. Application de l'acide obtenu dans l'industrie alimentaire.
