Abstract

여러 농도의 pinacol과 30 mM의 2, 3, butanediol, ethylene glycol의 전극-전해질 계면에서의 미분 용량을 1.0 M 황산과 sodium sulfate용액상에서 적하수은 전극(D.M.E.)으로 측정하였다. 산용액과 중성용액에서 계면미분용량-전위곡선은 Frumkin-Damaskin 등온 흡착식으로 검토하였다.
a>0 일 때 pinacol, 30 mM의 2, 3-butanediol 및 ethylene glycol의 경우 D.M.E.의 표면피복률과 수은에서 최대 표면 과잉량을 1.0 M 황산과 sodium sulfate 용액상에서 D.M.E. 측정치로부터 계산하였다.
The differential capacitance at the electrode electrolyte interface were measured with dropping mercury electrode(D.M.E.) in 1.0 M sulfuric acid and sodium sulfate solutions with various concentration of pinacol and 30 mM of 2, 3-butanediol, ethylene glycol. In acidic and neutral solutions, the differential capacitance vs. potential curves were treated Frumkin-Damaskin adsorption isotherm. Then we calculate coverage of D.M.E. and maximum surface excess on mercury at a>0, obtained from D.M.E. measurement in solution 1.0 M sulfuric acid and sodium sulfate with various concentration of pinacol and 30 mM of 23-butanediol and ethylene glycol.
