Synthesis of new chelating surfactants from octyl D-glucopyranosiduronic acid and amino acids for metal flotation.
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.
