从化学反应动力学基本方程出发、结合有关复杂电化学反应理论的两条基本原则(并行反应独立原理和极化曲线叠加原理)并用表观速率常数来包容传质系数的方法,建立恒温、恒容、恒电位操作条件下的草酸电还原反应的电化学工程模型。本文还探讨了用电流观测法解析复杂电化学反应的表观动力学常数的可能性,并用该方法对模型进行了验证。
Based on the basic equations of chemical reaction kinetics, combining the two basic principles of complex electrochemical reaction theory (the principle of parallel reaction and the principle of polarization curve superposition) and using the apparent rate constant to accommodate the mass transfer coefficient, a method of constant temperature and constant Electrochemical engineering model of oxalic acid reduction reaction under the condition of constant capacitance and constant potential. The paper also discusses the possibility of using current observational method to analyze the apparent kinetic constants of complex electrochemical reactions and validates the model with this method.
