Abstract

A solubility enhancing aqueous composition comprising a first solution comprising an anionic component comprising sulfate ions, alone or in combination with bisulfate ions, having a concentration from about 8.00 moles per liter to about 13.00 moles per liter of the first solution volume, and a cationic comprising ammonium ions having a concentration from about 1.45 moles per liter to about 2.01 moles per liter of the first solution volume, combined with a volume of water at least equal to the volume or weight of the first solution forming a second solution is provided. Variations of this general composition are also provided. The compositions are useful for enhancing solubility of a variety of molecules, typically metal ions.

Claims (9)

1. A solubility enhancing aqueous composition consisting essentially of an anionic component consisting essentially of sulfate ions, alone or in combination with bisulfate ions, having a concentration from about 8.00 moles per liter to about 13.00 moles per liter of the composition volume; a cationic component consisting essentially of ammonium ions having a concentration from about 1.45 moles per liter to about 2.01 moles per liter of the composition volume; and hydrogen ions in a concentration from about 17.38 mols per liter to about 21.68 moles per liter of the composition volume.

2. The composition of claim 1 , wherein said composition is substantially free of solids.

3. The composition of claim 1 , wherein said composition is free of solids.

4. A solubility enhancing aqueous composition comprising an anionic component comprising sulfate ions, alone or in combination with bisulfate ions, having a concentration from about 8.00 moles per liter to about 13.00 moles per liter of the composition volume; a cationic component comprising ammonium ions having a concentration from about 1.45 moles per liter to about 2.01 moles per liter of the composition volume; and hydrogen ions in a concentration from about 17.38 moles per liter to about 21.68 moles per liter of the composition volume.

5. The composition of claim 4 , wherein said composition is substantially free of solids.

6. The composition of claim 4 , wherein said composition is free of solids.

7. A solubility enhancing aqueous composition consisting of an anionic component consisting of sulfate ions, alone or in combination with bisulfate ions, having a concentration from about 8.00 moles per liter to about 13.00 moles per liter of the composition volume; a cationic component consisting of ammonium ions having a concentration from about 1.45 moles per liter to about 2.01 moles per liter of the composition volume; and hydrogen ions in a concentration from about 17.38 moles per liter to about 21.68 moles per liter of the composition volume.

8. The composition of claim 7 , wherein said composition is substantially free of solids.

9. The composition of claim 7 , wherein said composition is free of solids.
