Synthesis of sugar-based chelating surfactants for metal removal from wastewater

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.
