采用循环伏安扫描法、恒电流阶跃法研究了黄铁矿电极在丁基发原酸钾溶液体系中的电化学行为，根据电化学试验结果可以判定，黄药在黄铁矿电极表面形成双黄药；双黄药的形成是分步进行的，首先会发生黄原酸根离子的电化学吸附，然后再氧化成双黄药．由恒电流阶跃试验结果可以建立双黄药形成的氧化动力学方程，由此方程可以判定黄铁矿表面双黄药形成速率的大小．
Cyclic voltammetry and galvanostatical method were used to study the electrochemical behavior of pyrite electrode in potassium butyrate solution. According to the results of electrochemical test, the electrochemical behavior of pyrite electrode was observed on the surface of pyrite electrode Double xanthate; Double xanthate formation is step-by-step, the first occurrence of xanthogen ion electrochemical adsorption, and then re-oxidation into the double xanthate. Based on the results of constant current step test, the oxidation kinetics of luplene can be established, and the equation can determine the formation rate of lixiviant on pyrite surface.
