将超重力场应用到氯碱电解过程中,采用线性扫描法、计时电流法和交流阻抗法研究了超重力对析氢反应和析氯反应的影响,并进一步考察了氯碱电解槽电压随重力系数的变化规律.结果表明,超重力能够强化析氢反应和析氯反应的进行;相对于常重力条件,气泡更容易从电解液中溢出,溶液电阻随重力系数增加而降低;氯碱电解槽电压也随重力系数的增加而降低,并且电流密度越大,槽电压降低的程度越大.
The super gravity field was applied to chlor-alkali electrolysis. The effects of super gravity on hydrogen evolution reaction (HER) and chlorine evolution reaction (CER) were investigated by linear sweep voltammetry, chronoamperometry and electrochemical impedance spectroscopy (EIS). The relationship between the cell voltages and gravity coefficient was studied. The results indicated and gas product was easier to spillover from solution coefficient, The cell voltages also decreased with the the larger the degree of cell voltage reduction. that, the gas evolution reactions were intensified by super gravity The solution resistance would reduce with the increase of gravity increase of gravity coefficient, and the higher the current density,
