- W425944897 abstract "バナジン溶液を塩化第一スズで還元した後にチオシアン化カリウムを加えて生成させた黄緑色の錯化合物を有機溶剤によって抽出分離しこの抽出液の吸光度をBeckman DU型分光光度計を用いて測定した結果, 波長395mμに極大吸収を有する吸収スペクトルを得た。溶剤として酢酸エチルまたはメチルイソブチルケトンを用いた場合が最も吸光度が大でイソアミルアルコールおよびイソブチルアルコールがこれにつぐ。バナジン錯塩はベンゼン, 四塩化炭素, クロロホルム等では抽出されない。この方法によってバナジン10γ～100γの定量が可能である。チタン, コバルト, モリブデンおよび鉄等の共存はバナジンの吸光度測定に妨害となった。" @default.
