XAFS Determination of Pb and Cd Speciation with Siderophores and the Metal/Siderophore/Kaolinite System
Abstract
We provide evidence for hexadentate complexes of Pb2+ and Cd2+ with the trihydroxamate siderophore desferrioxamine B (DFO-B) at pH 7.5, and 9.0, respectively. Analysis of the species of Pb2+ and Cd2+ adsorbed at the surface of kaolinite clay under the same pH conditions and in the presence of DFO-B indicate that Pb2+ is sorbed as a metal-siderophore complex while Cd2+ is not.
