| Abstract: | The solvent extraction of gold and the structure of the organic phase were studied by labelled 198 Au and FTIR spectroscopy. Two supermolecular models for the extracting species in organic phases were proposed, and their aggregation was found with the increase of gold content in the organic phase. |
