| Outline of Final Research Achievements |
The objective of this study is to develop a new analytical method enabling a rapid and effective sorting of scrapped materials, by using laser-induced plasma - optical emission spectrometry (LIPS) under ambient atmosphere. In the recycling process of steel materials, especially such as high tensile-strength steels, it is important to save minor-alloyed elements: Mn, Cr, Ni, Co, V, and W, which are added to obtain the property of the high-grade steels, and thus to maintain the quality of the recycled steel materials. For this purpose, it is desired that scrapped steel materials will be able to be separated by their compositions of the alloyed elements. In this study, we could develop a LIPS apparatus which was suitable for this type of analysis.
