DIRECT SPECIATION OF SULFUR IN MARINE SEDIMENT BY HIGH-RESOLUTION PIXE
Preview AbstractChemical shifts of Kα1,2 line of sulfur in marine sediments were measured with in-air high-resolution PIXE in order to examine the possibility of direct speciation of sulfur in such environmental substances. Change of chemical states of sulfur along the depth in the sediments was observed. Oxidation of the sediment samples by air was also examined. Problems to be improved for exact speciation are discussed.
