摘要
采用静态失重试验与电化学测试方法测量了在不同浓度、种类的酸溶液中锌和铁的反应速率问题,测试表明,铁和锌在酸中反应速率取决于在此电流密度下的析氢超电势,当电流密度较小时,纯铁的反应速率大于纯锌。
This paper explores the reaction rate of zinc and iron in different concentrations and different kinds of acid solution by means of the static weight loss method and the electrochemical measuring technology. The reaction rate of zinc and iron in acid depends on hydrogen evolution over-potential of the current density. When the current density is low, the reaction rate of iron is higher than that of zinc, high current density on the contrary.
