Synthesis of sugar-based chelating surfactants for metal removal from wastewater
摘要:
Four chelating surfactants were synthesized in a few steps from octyl D-glucosides. Their main interfacial properties were determined, and their flotation properties were evaluated on a laboratory scale using Fe(III) as a model contaminant metal. The performance on metal extraction was mainly dependent on the complexing functional group, but the surfactant efficiency was also important. (C) 2008 Elsevier Ltd. All rights reserved.

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. (C) 2010 Elsevier Ltd. All rights reserved.
