Application of sequential extraction with supercritical CO(2), subcritical H(2)O, and an H(2)O/CO(2) mixture for estimation of environmentally mobile heavy metal fractions in sediments

Results from use of a new isolation procedure based on sequential extraction with supercritical CO(2), subcritical H(2)O, and an H(2)O/CO(2) mixture in the same supercritical fluid extractor have been compared with results from the BCR-recommended three-step sequential extraction procedure. The new...
