| Research Abstract |
It was found that arsenic and antimony in iron and steel were determined with a good precision at a few ppm of concentration level by using of a new developed energy dispersive X-ray analyzer. Iron nails of the Edo era were analyzed by an X-ray fluorescence analysis with this analyzer and other chemical analysis, an atomic absorption spectrometry, a laser ICP mass spectrometry and a neutron activation analysis. It was estimated by a comparison of these analytical results that the property of the iron nails was heterogeneous. The iron nails used for Toji temple at the Kamakura to Edo era were analyzed. As a results, the origin of feed materials for these nails were divided into five groups by the indicator of As/Sb concentration ratio.
