分析了用旋转圆柱形膨胀金属阴极的连续不分隔式电化学反应器去除稀溶液中的镉。确定了阴极外加电压、扩张金属网的大小和取向以及入口镉浓度对电极性能的影响。结果表明，镉可以从稀溶液(入口浓度范围为5-50 mg dm−-3)中脱除，根据操作条件的不同，可获得35-40%的高转化率。因此，最低残留镉浓度为3 mg dm−3。随着镉浓度的降低，比能耗从0.6kWhmoL−1增加到2kWhmo1。版权所有(C)2003化学工业学会
The removal of cadmium from dilute solutions using a continuous undivided electrochemical reactor with a rotating cylinder cathode of expanded metal is analysed. The effects of cathodic applied potential, size and orientation of expanded metal meshes and inlet cadmium concentration were ascertained. The results show that cadmium can be removed from dilute solutions (inlet concentration range 5–50 mg dm−3) with a high fractional conversion of between 35 and 40% depending on the operating conditions. Thus a minimal residual cadmium concentration of 3 mg dm−3 was achieved. The specific energy consumption increases from 0.6 to 2 kWh mol−1 as the cadmium concentration decreases.
