| 摘 要： | 在改进的传质池中通过在线检测草酸浓度，应用瞬时传质系数与平均传质系数，研究了各种方向及组合、不同电压、电极板形状与面积等条件下静电场对体系Cu2+-HDEHP-CCl4/H2O-H2C2O4伴随生成CuC2O4的传质过程特性。外场电压变化、电极面积可改变相间的传质速率，与传质方向成45°夹角的静电场作用对相界面传质速率的影响更为显著，表明相间传质阻力结构或相间传质层具有各向异性。

| Abstract: | Copper re extraction with oxalic acid from organic phase including Cu2+-HDEHP in tetrachloride carbon in a modified Lewis cell was studied. The concentration of oxalic acid was investigated by on-line detection using the method of conductance. The instantaneous and average coefficient of mass transfer were used to study the influence on interfacial mass transfer process by employing different direction, voltage, plate electrode and different area or their combination in Lewis cell. The research indicates that variation of voltage and electrode area can affect the velocity of mass transfer. But the electric field which moves an angle of 45° from the direction of mass transfer or their combination has prominent impact on interfacial mass transfer. It shows that the configuration of mass transfer resistance or interfacial layer has the characteristic of aeolotropism. |
