黄铜矿阳极溶解行为当面或在用细菌的 9 K 媒介的细菌的缺席修改了粉末在 30 deg C 的微电极被学习。它被发现那 .during 阳极溶解，许多中间的短暂反应发生在在 -0.075 V 和 -0.025 V 之间的潜力与辉铜矿和铜蓝的生产伴随(对 SCE ) 。在在 -0.1 和 -0.250 V 之间的低扫描潜力，铁离子在铁的形式被释放，但是在直到 0.7 V 的相对高潜力，它是铁的。Thiobacillusferrooxidans 的存在否定地让山峰水流增加和起始的山峰潜力移动，暗示分解氧化反应容易发生了，特别铁离子释放了，铁的氧化反应提高了。在在 -0.75 和 -0.5 V 之间的潜力的特征证明 Thiobacillus ferrooxidans 也贡献在氧化表面上形成并且在阳极法期间搬迁了的元素硫。在房间的增加的 ferric 能提高溶解反应，当在 pH=2 下面的增加的酸可能稍微妨碍这个过程时。阳极溶解动力学研究证明细菌的存在能死亡从 0.238 V 的腐蚀潜力到 0.184 V 和增加从 1.632 14 X 10 ~ 的腐蚀电流密度(-8) A/cm~2 to2.374 11 X 10 ~(-7)A/cm~2。

英文摘要：

The chalcopyrite anode dissolution behavior in the presence or absence of bacteria in 9 K media using bacteria modified powder microelectrode at 30 ℃ was studied. It is found that during the anode dissolution, many intermediate transient reactions occur accompanying with the production of chalcocite and covellite at potential between -0.075 V and -0.025 V （vs SCE）. At low scanning potential between -0.1 and -0.250 V, the iron ion is released in ferrous form, but at the relative high potential up to 0.7 V, it is the ferric one. The presence of Thiobacillus ferrooxidans makes peak current increase and the initial peak potential negatively move, hinting the decomposed oxidation reaction easily occurred and especially the iron ion released and ferrous oxidation reaction enhanced. The characteristic at potential between -0.75 and -0.5 V demonstrates the Thiobacillusferrooxidans also contributes to the element sulfur formed on the oxidation surface and removed during anode process. The added ferric in the cell could enhance the dissolution reaction, while the increased acid under pH=2 might slightly hamper the process. The anode dissolution kinetics studies show that the presence of bacteria could decease corrosion potential from 0.238 V to 0.184 V and increase the corrosion current deusity from 1.632 14×10^-8 A/cm^2 to 2.374 11×10^-7A/cm^2.
