BUNSEKI KAGAKU, 1960 金属コバルト中の純分を電解分析によって定量する方法を検討した.電解液としてピロリン酸ナトリウム-マンモニア溶液または炭酸アンモニウムアンモニア溶液を用いればコバルトの酸化物の析出にもとづく過大の誤差が生じることなく0.01%程度の誤差で定量が可能である.電流密度は0.25amp/dm2,電解温度は45～60℃,電解時間は約20時間,試料秤取量は1gにするを要する.電流密度が高くなったり,電解温度が低くなると,異常析出がおこり電着物が黒色となる.

Term "nano" in electroanalysis: A trendy prefix or a new stage of its development? [PDF]
, 2013 The use of term "nano" in electroanalytical methods (electroanalysis) is considered. Attention is paid to the recent trend in the development of electroanalysis in context of modern views on processes in the double electric layer, or interface, as a ...

[Electroanalysis of nifedipine].
Acta pharmaceutica Hungarica, 1990 Nifedipine is an electrochemically active compound. Reducibility of 2-nitrophenyl group on dropping mercury electrode renders polarographic determination of nifedipine possible. Reductive half-wave potential of nitro group depends on saturation of neighbouring pyridine ring i.e.
