据荷兰《湿法冶金》杂志报道,波兰克拉科夫冶金学院研究了铜阳极中铅和氧含量对电解精炼铜过程中阳极钝化过程的影响。研究结果表明,阳极中铅含量0.003～2％时,实际上不影响阳极钝化时间。当氧含量大于铅的化学计算量时,特别是在高电流密度和氧含量大情况下,氧的影响是明显的。阳极 According to Dutch “Hydrometallurgy” magazine, Krakow Institute of Metallurgy in Poland studied the effect of lead and oxygen in copper anodes on anodic passivation during electrolytic refining of copper. The results show that the anode lead content of 0.003 to 2%, in fact, does not affect the anode passivation time. When the oxygen content is greater than the stoichiometric amount of lead, the effect of oxygen is significant especially at high current densities and oxygen contents. anode
