The percent metal recovery for lead, chromium and mercury from their EDTA complexes was 99.7, 67.9, and 92.0 percent, respectively. Cadmium could not be recovered from its EDTA chelate. The percent EDTA recovery is equal to the percentage of metal electroplated from the complexes.

Predicting Stability Constants of Various Chelating Agents Using QSAR Technologyg the activity of the chelator is often needed (Hong.1995). The list of chelating substances is long and there is little information in the literature other than specific test information which will provide guidance to the worker as to the selection of the optimum chelator.

However, in the case of sand, the removal of the contaminant is indicated to be a combination of displacement, dispersion/mobilization and solubilization. The low pressure buildup, when using colloidal gas dispersions, makes it a favorable fluid for field applications.

Emerging Technologies in Hazardous Waste Management VIIin an applied perspective. Focus on this outcome has been provided by representative examples in this volume of the series. However, while definite progress is being made, additional discovery is needed to further advance the basic science and technology, and to make translation into practice more of a reality.

Granular Iron Oxide as A Catalyst in Chemical Oxidation of Organic Contaminantsantly in the presence of granular iron oxide mineral, goethite. It is believed that the hydroxyl radical produced by the catalytic decomposition of H.O. or 0, over the goethite surface was responsible of oxidation of the surface-bound organic compounds. The oxidation rate of the organics was directl
