氰化解吸液中电沉积金的热力学分析

Thermodynamic analyses of gold electro-deposition from the disabsorbed cyanide solution

利用热力学数据，结合有关热力学原理，计算了氰化解吸液中电沉积金的电极反应在常温及高温水溶液中的标准电极电位ε°Ｔ及电极电位εＴ（温度范围２５—１５０℃）；对载金活性炭氰化解吸液中电沉积金的阴阳极反应及贱金属与金的共沉积进行了热力学分析。

The ε°T and εT of electrode reactions of gold electro-deposition in the disabsorbed cyanide solution at normal and high temperatures were calculated by using of thermodynamic data and principles(temperature range:25～150℃)The thermodynamic analysis of the electrode reaction of gold electro-deposition in disabsorbed cyanide solution containing gold loaded actiyated carbon was made, And the thermodynamic analysis of codeposition of base metal and gold was made too.
