光量子放射化法による河川堆積物の非破壊多元素分析 Nondestructive Multielement Photon Activation Analysis of River Sediment 佐藤, 允美 gamma-spectrophotometry 自然環境 環境汚染問題 A nondestructive method by photon activation analysis with 30 MeV bremsstrahlung followed by high-resolution gamma-spectrophotometry has been developed for the multielement determination in water pollution source emissions. The sample materials subjected to analysis were NBS standard references and river sediments. Simultaneous irradiation of the sample with Japanese standard rock, JB-1, and the synthetic multielement standards containing 33 elements has shown that the technique is successful with regard to the capability of determining 16 elements in a single sample. These are As, Ba, Ca, Ce, Co, Cr, Fe, Mn, Na, Nb, Ni, Rb, Sr, Ti, Y, Zr. The method is quite simple and gives good reproducible results. 岩手大学人文社会科学部 1980-07-21 jpn departmental bulletin paper VoR https://doi.org/10.15113/00013826 https://iwate-u.repo.nii.ac.jp/records/13832 10.15113/00013826 AN00000256 03854183 Artes liberales 26 129 141 https://iwate-u.repo.nii.ac.jp/record/13832/files/al-no26p129-141.pdf application/pdf 619.8 kB 2016-11-14
