Abstract
구리이온의 flux에 대한 실험식을 만들어 전류밀도, 도입유속에 따른 구리이온 제거효율을 계산하여 실험값과 비교하였다.
구리온의 flux에 대한 식은 feed중 구리이온 농도에 비례하였고 확산과 대류영향을 제외한 경우 구리이온 flux는 전류밀도에 선형적으로 비례하였다.
연속식 실험에서 구리이온 및 황산의 제거효율은 도입유속 2.3 ml/min, 전류밀도 285.7 A/㎡에서 구리이온은 65 % 이상, 황산은 70 % 이상이었다.
황산에 대한 전류효율은 도입유속이 클수록 전류가 낮을수록 높게 나타났으며 실험범위 3.1∼15.0 ml/min, 0.3 A∼1.2 A 중에서 유속 15.0 ml/min, 전류 0.3 A에서 황산의 전류효율은 75.4 %로 가장 높게 나타났다.

An experimental formula is proposed and the calculated ion removal efficiencies have been compared with experimentally measured ones with variation of current density and input flow rate.
The copper ion flux has been found to be proportional to the copper ion concentration in feed. The copper ion flux without diffusion and convection has been found to be linearly proportional to the current density.
When the input flow rate was 2.3 ml/min and the current density was 285.7 A/㎡ in the continuous system, the removal efficiencies of copper ion and sulfuric acid were 65% and 70 % respectively.
Current efficiency of sulfuric acid showed the highest value in the flow rate of 15.0 ml/min and the current of 0.3 A, in the experimental range of 3.1-15.0 ml/min for the flow rate and of 0.3-1.2 A for the current.
