dc.description.abstractThe adsorption of strontium (Sr) by bentonite in the presence of various dicarboxylic and aromatic acids was investigated. Strontium uptake was strongly influenced by ionic strength, but not by the presence of the organic acids. However, Sr significantly affected the binding of the organic acids. X-ray diffraction (XRD) results suggested that the interlayer spacing of MX-80 bentonite was affected by the presence of Sr, particularly when organic acids were also present. Cation exchange is the major Sr uptake mechanism, and competition with divalent ions should be considered. Thermodynamic modelling and XRD results suggested that surface precipitation of Sr occurs at high pH values. © 2015, Springer.en_AU
