以含金银铅废料制成贵铅为原料，利用电化学热力学和动力学理论，对贵铅电解法实现金银与铅的分离和得到纯铅的电极过程极化行为与工艺条件的关系进行了研究。从而确定了贵铅电解时的电解液组成为［ｐｂ２＋］７０ｇ／Ｌ，温度为４０℃，β－萘酚／胶联合添加剂等工艺条件．同时根据动力学的研究证明了贵铅电解的电极反应速度受扩散控制，其扩散速度常数Ｋ扩＝１．９１７×１０－３ｃｍ／ｓ。扩散层厚度为０．００５１ｃｍ，在ηｋ＝７５ｍＶ时的阴极过程活化能为１６．１０ｋＪ／ｍｏｌ，为贵铅电解工业分离回收金银铅提供了可靠的理论依据和设计参数。
Based on the electrochemical thermodynamics and kinetic theory, the lead-based electrolysis method is used to separate the gold, silver and lead and to get the relationship between the polarization and electrodeposition process of pure lead Study. Thus, the composition of the electrolyte during the lead electrolysis was determined to be [pb2 +] 70 g / L, the temperature was 40 ° C., and the β-naphthol / glue combination additive and other process conditions were determined. At the same time, according to the kinetic studies, it is proved that the electrode reaction rate of your lead electrolysis is controlled by diffusion. The diffusion rate constant K is 1.917 × 10-3cm / s. The thickness of the diffusion layer is 0.0051 cm, the activation energy of the cathode at ηk = 75 mV is 16.10 kJ / mol, which provides a reliable theoretical basis and design parameters for the separation and recovery of gold, silver and lead from the lead industry.
