The most important result of this work is to show that water-insoluble chelators have the same yield at extracting metal ions from contaminated soils when they are dissolved in a mostly aqueous, non-toxic solvent solution (e.g. a 99% water-1% ethanol mixture), as when more toxic systems (e.g. a 50% water-50% acetone mixture) are used. In addition, the solvent solution can be composed mainly of water, with only a very small amount (1% in our case) of solvent added to dissolve the complexing agent. These results extend and generalize those previously presented by Mauri and coworkers.

Abstract

The most important result of this work is to show that water-insoluble chelators have the same yield at extracting metal ions from contaminated soils when they are dissolved in a mostly aqueous, non-toxic solvent solution (e.g. a 99% water-1% ethanol mixture), as when more toxic systems (e.g. a 50% water-50% acetone mixture) are used. In addition, the solvent solution can be composed mainly of water, with only a very small amount (1% in our case) of solvent added to dissolve the complexing agent. These results extend and generalize those previously presented by Mauri and coworkers.
