| Abstract: | A new family of surfactants with metal-chelating properties was synthesized in few steps from octyl d-glucopyranosiduronic acid. The complexing function was either a carboxylic acid or a hydroxamic acid function introduced after coupling with glycine, aspartic acid, or glutamic acid and finally hydroxylamine. Interfacial properties were determined. Flotation experiments on a laboratory scale have been performed with Fe(III) solutions as model contaminant metal. |
