Figure 2From: Adsorption of hydroxamate siderophores and EDTA on goethite in the presence of the surfactant sodium dodecyl sulfateAdsorption of EDTA and the siderophores DFOB (data from [21]) and DFOD onto goethite at pH 6 as a function of SDS concentration (0.01 M NaClO 4 , 7 g/L goethite, 24 h equilibration time). The total ligand concentration was 80 µM. Error bars indicate the standard deviation of three replicates.Back to article page
