引言霍耳-埃鲁法的电流效率,是在阴极上实际析出的铝量与按法拉第定律在阴极上理论析出的铝量之比。电流效率受许多变量的影响,如温度、极距、电流密度、电解质成分与电解槽几何尺寸等,而单独改变这些变量在工业电解槽上是不可能的。这只有在试验电解槽上才能做到,但试验电解槽也绝不是工业电解槽的精确模型。因 INTRODUCTION The current efficiency of Hall-Elufa is the ratio of the amount of aluminum actually precipitated on the cathode to the theoretical amount of aluminum precipitated on the cathode according to Faraday’s law. Current efficiency is affected by many variables such as temperature, pole pitch, current density, electrolyte composition and cell geometry, and changing these variables alone is not possible with an industrial cell. This can only be done on a test cell, but the test cell is by no means an accurate model of an industrial cell. because
