近年来,I.Newman等已证明电解液流动的填充多孔电极比普通多孔电极和流动的非多孔体电极传质速率高,比表面积大。因此适用于从稀溶液中提取重金属离子的实际生产要求。 为使电解液在填充床内有较高的传质速度和必要的停留时间,并且在填充床内得到 In recent years, I. Newman et al. Have demonstrated that the porous electrolyte filled porous electrode has a higher mass transfer rate and a larger specific surface area than the ordinary porous electrode and the flowed non-porous electrode. Therefore, it is suitable for the actual production requirements of extracting heavy metal ions from dilute solution. In order for the electrolyte to have a higher mass transfer rate and the necessary residence time in the packed bed and to be obtained in the packed bed
