Abstract	標準酸化還元電位が近接する銅とアンチモンを示差パルスアノーディックストリッピングボルタンメトリーにより簡便に直接同時定量できる高感度分析方法を開発した．電極表面が大きく多孔性であれば，電着析出物の電極内部への拡散と選択的な溶出が起こり得る．そこで本研究では，カーボンペーストがストリッピングボルタンメトリーの作用電極に最適であることを明らかにし，再現性のある電極が容易に作製できる器具を考案してその作製条件（オイルの種類と混合割合など）について検討した．その結果，低くて安定なバックグラウンド電流と高い再現性が得られるカーボンペースト電極を作製できた．この電極を用い，銅とアンチモンの重複ピークの分離にはヨウ化物イオンとL(+)-アスコルビン酸の添加が有効であることを見いだし，実際に鉄鋼材料の分析に応用して満足な結果を得た．
