Measurement and Evaluation

Matsuo, Motoyuki
Doctor of Science
Environmental and Analytical Chemistry, Geochemistry, Radiochemistry
Matsuo Lab


Prof. Matsuo began his academic career as an undergraduate student at the Department of Chemistry in the University of Tokyo. He received a Doctorate of Science from the University of Tokyo in 1983. He trained as a Ramsay Memorial Fellow at the Department of Inorganic and Structural Chemistry in the University of Leeds, England (1987-1989).

Prof. Matsuo's research interests are in the environmental evaluation by the state analysis of elements. His attention has been paid to the chemical states of iron (oxidation states, coordination, magnetic properties, etc.), that is included in various environmental or geochemical samples. 57Fe Moessbauer spectroscopy is one of the most useful means for characterizing the chemical states of iron in a wide variety of natural samples. This technique has been employed successfully in his investigations on airborne particles and estuarine sediments, etc. X-ray absorption fine structure (XAFS) spectroscopy has also been applied to characterization of iron and other elements. The distribution and movement of elements in the environment are also studied by using high sensitivity elemental analyses such as neutron activation analysis, prompt gamma-ray analysis and ICP-MS.
