Abstract

Metal ions in solid and liquid materials can be extracted by supercritical CO2 containing a suitable ligand, Bis(trifluoroethyl)dithiocarbamate is an effective ligand for the extraction of transition metals and non-metals in supercritical CO2. Fluorinated ß-diketones and tributyl phosphate in supercritical CO2 exhibit a positive synergistic extraction for the lanthanides and actinides from solid and liquid samples. Triazole containing crown ethers can also be used for selective extraction of heavy metals in supercritical CO2. © 1995, The Japan Society for Analytical Chemistry. All rights reserved.
