Abstract

L’invention fournit des compositions et des procédés pour éliminer/récupérer des ions de métaux lourds dans des solutions contenant de l’acide phosphorique par addition de réactifs contenant au moins un composé organothiophosphoré et au moins un composé de 2- mercaptobenzothiazole à une solution ou suspension d’acide phosphorique par voie humide pour former des complexes d’ions de métaux lourds, et pour séparer les complexes d’ions de métaux lourds de la solution.The invention provides compositions and methods for removing/recovering heavy metal ions from solutions containing phosphoric acid by adding reagents containing at least one organothiophosphorus compound and at least one 2-mercaptobenzothiazole compound to a solution or wet phosphoric acid slurry to form heavy metal ion complexes, and to separate the heavy metal ion complexes from solution.
