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90~120 g/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。

Abstract: The influence of additive and technological parameter on cathode process of electrodepositing Pb in PbSiF₆-H₂SiF₆electrolytic 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 40~120 g/L,H₂SiF₆ as 90~120 g/L, sodium wood-sulfonate additive as 4 gL, high quality deposit Pb was obtained.
