| 中文摘要 | 本研究以CuS□/N□S□溶液在垂直式流體化床中測量二維之電流電位分布。並且建立了一個教學模式來描述在極限電流下的矩形垂直式流體化床。進而比較模擬與實驗而得到一致 結果。從極限電流的測量中,可得到質傳的關係式如下: □=1.864□ 10<□<140 在流體化床中以循環操作品收金屬也已探討,可測得銅離子從900mm降至3ppm以下。而且實驗的結果也相當符合理論模擬的結果。 |
| 英文摘要 | Two-dimensional current and potential distribution in a flow-by packed bed electrode have been measured with the test solution of CuS□/N□□。A mathematical model describing a rectangular flow-by packed bed electrode below limiting currents has been enveloped. Comparisons of current and potential distributions between the simulated and experimental results have been made, and fairly good agreements with each other have been reached. A mass transfer correlation has been obtained from limiting-current measurements, and it can be expressed as follows □=1.864□ 10<□<140 The performance of metal recovery by packed bed electrodes in circulating operation has been studied, and the concentration of cupric ion was reduced from 900 ppm to below 3 ppm. The experimental concentration-time curves are well predicted from the numerical results of themathcmatical model. |
