用循环伏安法作为测试手段，研究了块状黄铜矿（CuFeS2）电极在没有和有嗜温微生物存在情况下的电化学行为．对于氧化亚铁硫杆菌、氧化硫硫杆菌和氧化亚铁钩端螺旋菌应用的是基本培养物．结果表明，随着细菌的处理，黄铜矿的反应活性逐渐加强．当施加的电位增大时，经微生物处理后的黄铜矿阳极溶解过程与钝化层的破坏有关．表面产物的分析说明细菌浸出试验中黄铜矿被一层表面膜所覆盖从而阻碍了它的溶解．因此，由于表面结构的改变，细菌浸出样品的静电位可能增加．
Cyclic voltammetry (CV) was used as the test method to study the electrochemical behavior of bulk chalcopyrite (CuFeS2) electrode in the absence of mesophilic microorganisms. For cultures of Thiobacillus ferrooxidans, Thiobacillus thiooxidans and Leptospira ferrooxidans, base cultures are used. The results showed that with the treatment of bacteria, the reactivity of chalcopyrite gradually strengthened. When the applied potential is increased, the anodic dissolution of the chalcopyrite after microbial treatment is related to the destruction of the passivation layer. Analysis of the surface product showed that the chalcopyrite was covered with a layer of surface film in a bacterial leaching test, hindering its dissolution. Therefore, the static potential of bacterial leaching samples may increase due to changes in surface structure.
