| Prior art processes for removal of one or more contaminant elements, including at least one of antimony, bismuth, and arsenic and optionally including iron, from electrolyte solutions of primary metals by solvent extraction with an organic phase including a hydroxamic acid, then precipitating at least part of the contaminant elements from the organic phase as sulfides, are improved by an additional step of re-extracting the organic phase with water before precipitating the sulfides from it. At least part of any arsenic present and, if desired, part of any antimony as well, may be re-extracted in this manner and subsequently recovered if desired, so that the overall process is made more economical. | ||||||

| Dans un procédé pour séparer des éléments parasites, à savoir arsenic, antimoine, bismuth et/ou fer, contenus dans des solutions électrolytiques de métaux de valeur, par extraction par solvant et récupération consécutive des éléments parasites précités, une solution électrolytique aqueuse de métaux de valeur d'acides minéraux est ajoutée à un solvant organique faiblement hydrosoluble, renfermant un ou plusieurs acides hydroxamiques et les deux phases sont intimement mélangées. Les sulfures d'arsenic, antimoine et bismuth sont précipités à partir de la phase organique, séparés, et le fer extrait est ensuite extrait à nouveau et récupéré dans une phase aqueuse avec un complexant hydrosoluble. Avant la précipitation des sulfures, la phase organique est mise en contact avec de l'eau pendant une durée suffisante pour permettre la ré-extraction, et si nécessaire, l'arsenic et/ou l'antimoine ré-extraits dans la phase aqueuse sont précipités par réduction d'une manière connue en soi et re-traités sous forme de sous-produit. | ||||||
| 6 | Process for separating antimony from acidic solutions containing same with an organic diluent containing a polyol | US466319 | 1990-05-04 | US5093090A | 1992-03-03 | Renato Guerriero; Italo Vittadini |
| There is disclosed a method for the separation of antimony from acidic solutions which contain antimony, alone, or together with other metallic ions, by extracting antimony with an organic, water-immiscible, polyol-containing diluent. The method comprises the steps of contacting the antimony-containing acidic solution with a water-immiscible organic diluent containing at least one polyol dissolved therein, preferably a diol, said polyol serving to extract the antimony. The polyol serves to selectively extract the antimony from the acidic solution to the exclusion of other metallic ions such as copper and nickel. | ||||||

| A method for separating .sup.213 Bi from a solution of radionuclides wherein the solution contains a concentration of the chloride ions and hydrogen ions adjusted to allow the formation of a chloride complex. The solution is then brought into contact with an anion exchange resin, whereupon .sup.213 Bi is absorbed from the solution and adhered onto the anion exchange resin in the chloride complex. Other non-absorbing radionuclides such as .sup.225 Ra, .sup.225 Ac, and .sup.221 Fr, along with HCl are removed from the anion exchange resin with a scrub solution. The .sup.213 Bi is removed from the anion exchange resin by washing the anion exchange resin with a stripping solution free of chloride ions and with a reduced hydrogen ion concentration which breaks the chloride anionic complex, releasing the .sup.213 Bi as a cation. In a preferred embodiment of the present invention, the anion exchange resin is provided as a thin membrane, allowing for extremely rapid adherence and stripping of the .sup.213 Bi. A preferred stripping solution for purification of .sup.213 Bi for use in medical applications includes sodium acetate, pH 5.5. A protein conjugated with bifunctional chelating agents in vivo with the NaOAc, to receive the .sup.213 Bi as it is being released from the anion exchange resin. | ||||||

| PURPOSE: To remove selectively and efficiently Bi and/or Sb from an aqueous soln. acidified with sulfuric acid by bringing the soln. contg. dissolved Bi and/ or Sb into contact with a phosphomethylamino type chelate resin. CONSTITUTION: An aqueous soln. contg. dissolved Bi and/or Sb acidified with sulfuric acid such as a copper electrolytic soln. is continuously passed through a layer of a phosphomethylamino type chelate resin packed in a column. By the contact of the soln. with the chelate resin, Bi and/or Sb can be removed selectively and efficiently, so the copper electrolytic soln. or the like is easily purified. The contact is effectively carried out at ambient temp., it is not required to adjust especially the concn. of sulfuric acid in the soln., and the soln. is handled simply.
