| 摘要 |
The present invention relates generally to methods for making essentially anhydrous silver thiosulfate ion complexes. The method comprises: a) providing an aqueous solution of silver thiosulfate ion complexes; b) adding a solvent to said solution to create a biphasic separation wherein said silver thiosulfate ion complexes separate into a single phase; c) collecting said single phase containing said silver thiosulfate ion complexes; and d) removing water from said single phase such that said silver thiosulfate ion complexes are essentially anhydrous.
