Abstract
Procédé pour purifier de l'acide phosphorique qui a été soumis au préalable à une extraction par solvant. On met l'acide phosphorique contenant des résidus de véhicule organique en contact avec une matière sorbante qui retient les résidus de véhicule organique. La matière sorbante peut consister avantageusement en plâtre 1 mis par exemple sous la forme d'un gâteau de filtration au travers duquel on fait passer (en 2) l'acide phosphorique à purifier. Application pour la récupération de l'uranium contenu dans l'acide phosphorique.
