摘要
本文研究了黄药体系中磁黄铁矿电极表面吸附的双黄药的稳定性。采用恒电位阶跃法确定了丁基黄药离子在磁黄铁矿表面的扩散系数D为2.25×10-6cm2/s;采用循环电位扫描法确定丁基双黄药还原为黄药离子的阴极反应为一不可逆电化学反应,结合恒电流阶跃法建立了双黄药在磁黄铁矿电极表面还原解吸的电化学还原动力学方程。
In this Paper, the electrochemical behaviors of pyrrhotite electrode in butyl xanthate solution arestaled. A series of tests by potentiostatic steps, galvanostatic steps and cyclic potential seanning had been carredout on pyrrhotite electrode . The results demonstrate that the stability of dixanthogen adsorbed on pyrrhotite surface is affected by kinetic behavior of dectrochemical reduction . The equations of them are set up.
