【摘要】 采用动电位法研究了在ＰｂＳｉＦ６Ｈ２ＳｉＦ６电解液体系中，添加剂及工艺参数对电沉积Ｐｂ阴极过程的影响，探讨了电沉积Ｐｂ过程的电化学反应机理。研究结果表明，控制电解液含Ｐｂ量为４０～１２０ｇ／Ｌ，Ｈ２ＳｉＦ６为９０～１２０ｇ／Ｌ，添加剂木质磺酸钠为４ｇ／Ｌ时，可以获得高质量的Ｐｂ沉积物更多还原

【Abstract】 The influence of additive and technological parameter on cathode process of electrodepositing Pb in PbSiF 6 H 2SiF 6 electrolytic system was investigated by motional electric potential. The electrochemical mechanism of the process is indicated. The experimental results showed that controlling Pb in electrolyte as 40～120g/L,H 2SiF 6 as 90～120g/L, sodium wood sulfonate additive as 4g/L, high quality deposit Pb was obtained.更多还原
