Cobalt and other metals, spiked onto lab coats, can be removed by supercritical fluid carbon dioxide (SC-CO2) containing mixed chelating agents Cyanex 302 and dithiocarbamate, as well as by a water-in-CO2 microemulsion. The extraction efficiencies for both methods can exceed 90%. The mixed-ligand ap...
