Abstract
Supercritical fluids are versatile solvents in organic separations and extractions. The application of supercritical fluids to metal extractions is a recent extension of this technology. This application requires that three criteria be met: enhanced ligand selectivity/specificity, increased solubility of the ligand in the supercritical fluid, and ease of metal removal from the ligand after extraction. Recent efforts are described studying metal complexation and organometallic chemistry in supercritical fluids as a function of pressure and temperature. These investigations involve high-pressure NMR and FTIR studies of organometallic compounds in fluid solutions. The application of these spectroscope techniques to the investigation of inorganic species in supercritical fluids is described in conjunction with the molecular details revealed of fluid solution structure and metal complexation dynamics.
