简介:研究在AlC13-NaCl熔融盐体系中进行电精炼废旧铝合金回收金属铝。以铝合金为阳极,通过直流电沉积在铜阴极上得到铝涂层。在170°C、电流密度100mA/cm2下电解4h,得到的沉积物铝的纯度大约为99.7%,电流效率为44%~64%,每千克铝消耗电能3~9kW·h。探讨阴极电流密度、电解质成分和电解时间及温度等对铝沉积电流效率的影响。结果表明:在AlCl3和NaCl摩尔比为1.3~1.9时,AlCl3和NaCl摩尔比对电流效率的影响很小,升高电解温度有利于提高电流效率;但是延长电解时间或增大电流密度会导致电流效率降低。电流效率的降低主要是由于沉积的铝呈现枝状晶或粉化而易从阴极上脱落到电解质中所致。
