“…Methods for speciation analysis are particularly welcome for elements for which the oxidation state directly affects species mobility and toxicity. An HR DGT technique used with LA-ICP-MS analysis enabled 124 the selective and simultaneous 2D chemical imaging of As III , Cr III and Sb III at the sub-mm scale for the first time. Whereas trivalent species were selectively accumulated on a mercapto-functionalised attapulgite binding gel, <2% of the higher oxidation state species were accumulated.…”
