- W641570224 abstract "原子力施設から放出されることが予想される長半減期核種を海水中から分別捕集し, Nal (Tl) 検出器を用いるγ線スペクトロメトリーによって分析する方法を検討した。水和酸化鉄 (III) の沈殿をアンモニア水の代わりにピリジンを用いて生成させると, 沈殿時のpHを6～7に容易に調節でき, 2, 3の金属との錯塩形成も手伝って59Fe, 95Zr, 144Ce, 106Ruを95%以上の共沈率で捕集でき, 90Sr, 137Csはまったく, 60Co, 65Znは一部分しか共沈せず, 容易に分別ができる。ピリジンおよびFe3+の添加量を変えて実験し, 各核種の鉄共沈に対する挙動を知ることができた。" @default.
