闪锌矿的能带宽和绝缘性质，限制了用常规电化学方法研究它与浮选药剂的界面化学反应特性．改进后的电极在闪锌矿被铜离子或其它重金属离子活化后，表面具备了传导性，由此，上述难点得以克服，只需将矿物电极浸入硫酸铜溶液中较短时间，就会使得它明显具有硫化铜的电化学活性。将闪锌矿置于pH4.6、含10－4MCuSO4溶液中活化后，可用循环伏安法对活化产物进行定量和定性的研究。研究结果表明，铜离子的活化效果明显地取决于活化时的电化学电位．当活化电位朝低于静电位方向变化时，活化作用会使得表面的含铜量逐渐增加；当活化电位朝高于静电位方向增加时，会使得含铜量减少。这些结果指出铜离子吸附的动力学过程和活化产物的化学组成（化学计量）均受电位所控制。
The energy bandwidth and insulating properties of sphalerite limit the use of conventional electrochemical methods to study its interfacial chemical reaction characteristics with flotation reagents. The improved electrode surface after sphalerite is activated by copper ions or other heavy metal ions, the surface has the conductivity, thus the above difficulties can be overcome, just the mineral electrode immersed in copper sulfate solution for a short time, it will make it Clearly have copper sulfide electrochemical activity. Sphalerite will be placed in pH4.6, containing 10-4MCuSO4 solution activation, cyclic voltammetry can be used to quantitatively and qualitatively studied the activation products. The results show that the activation of copper ions obviously depends on the activation of the electrochemical potential. When the activation potential changes below the static potential direction, activation will make the surface of the copper content gradually increased; when the activation potential increases above the electrostatic potential direction, will make the copper content decreased. These results indicate that both the kinetics of copper ion adsorption and the chemical composition (stoichiometry) of the activated product are controlled by potentials.
