The Journal of the Society of Chemical Industry, Japan, 1963 原子吸収分光光度法による鋳鉄中のマグネシウムの定量について鉄を除去した場合に必要な基礎的研究を行ない定量方法を確立した。マグネシウムを定量する場合,アルミニウムおよびケイ素は影響を与えるが,カルシウムの添加によってその影響は消失した。チタンは全く影響を示さなかった。クロムは3価として存在すれば影響しなかった。重クロム酸として存在するとマグネシウムの吸光度は増大するが,その割合はクロム量が増加しても一定であった。リンは空気-アセチレン炎では影響はあらわれなかったが,空気-プロパン炎の場合にはあらわれた。鋳鉄中のマグネシウムは試料溶液からメチルイソブチルケトン抽出で鉄を除去し,原子吸収分光光度法で定量する。この方法は操作が簡易迅速で結果も良好であった。

Bridging Model and Observed Stellar Spectra
, 2010 Accurate model stellar fluxes are key for the analysis of observations of individual stars or stellar populations. Model spectra differ from real stellar spectra due to limitations of the input physical data and adopted simplifications, but can be ...
