在多数情况下 ,锑和铋以有害痕量元素存在于电解液和金属材料中。在铜电解液中 ,锑和铋的含量决定电解铜的质量 ,当它们的含量达到一定值时 ,电解池中阳极 (粗铜 )的残极率上升 ,同时阴极 (精铜 )表面起瘤 ,从而造成精铜纯度下降 ,故需严格控制锑和铋的含量[1 ] 。吸光光度法测 In most cases, antimony and bismuth are present as harmful trace elements in the electrolyte and in the metal material. In copper electrolyte, the content of antimony and bismuth determines the quality of electrolytic copper. When their content reaches a certain value, the residual percentage of anode (blister) in electrolytic cell rises, and the surface of cathode (fine copper) Resulting in decreased purity of refined copper, it is necessary to strictly control the content of antimony and bismuth [1].
