| 摘 要： | 应用多种电化学方法确定了氯盐体系中硫化汞精矿悬浮电解的阳极反应不是HgS的直接氧化,而是Cl~-失去电子析出Cl_2的反应。硫化汞精矿在悬浮电解中的浸出实质上是氯化浸出。在电极表面被大量氯气泡覆盖之前,阳极过程受电化学极化控制并遵循Volmer-Heyrovsky机理。阳极反应的速度控制步骤随过电位的升高由首次电子传递向电化学脱附化。测定了阳极过程的电化学参数,提出了相应的动力学方程。并以分子轨道理论对反应机理进行了讨论。

| Abstract: | The anodic processes in suspension el ectrolysis of cinnabar concentrates in chloride system have beenstudied using several electorchemical techniques.It has been etermined that the anodic reaction is notthe oxidation of cinnabar but the oxidation of l~-.The anodic process is controlled by electrochemicalpolarization and is obedient to Volmer-eyrovsky mechanism.The relative electrochemical parametershave been determined and the kinetic quations proposed. |
