Direct speciation of ultra-trace platinum in marine ferromanganese oxides by wavelength-dispersive XAFS

Abstract Ultra-trace platinum (Pt) in marine ferromanganese oxides (FMOs) has remained inaccessible to direct XAFS analysis because of its extremely low abundance and severe interferences from co-existing elements. We achieved the first direct speciation of Pt at the 1 μg g−1 lev...
