Abstract
황산（0.1 M 및 1 M） 산성의 황산구리전해액(0.032 M Cu)으로 구리입자(0.5 ㎜)를 유동화시키는 직사각형-십자류(전해액-전류사이에) 유동층전극반응기내에서 층팽창률과 전류밀도를 변화하여 연속상 및 분산상전위를 각각 측정하고, 이로부터 연속상 및 분산상의 유효전기비전도도와 총괄유효전기비전도도를 산출하였다.
그 결과 연속상유효전기비전도도는 층다공률의 3.0승에 역비례하고, 분산상유효전기비전도도는 층다공률의 12.0승에 역비례하고, 총괄유효전기비전도도는 층다공률의 6.8승에 역비례하였다.

Potential profiles of continuous electrolyte phase and dispersed particle phase were measured in a fluidized bed electrode reactor of rectangular geometry. The reactor with solid copper particles（0.5 ㎜ in diameter） was used to deposit copper from acidified aqueous solutions (0.1 M and 1 M H2SO4) containing 0.032M of copper. Effective specific electrical conductivities of individual phase could be calculated from the potential profiles.
Results showed that the effective specific electrical conductivity of continuous electrolyte phase was inversely proportional to the 3.0 power of the bed porosity and proportional to the electrolyte specific electrical conductivity, the effective specific electrical conductivity of the dispersed particle phase was inversely proportional to the 12.0 power of the bed porosity, and the overall（or equivalent） electrical conductivity of the bed was inversely proportional to the 6.8 power of the bed porosity.
