Extended-DLVO模拟不同能源适应的Acidithiobacillus ferrooxidans与黄铜矿之间的相互作用
Interactions between Different Energy Sources Adapted Acidithiobacillus ferrooxidans and Chalcopyrite Simulated by Extended-DLVO
摘要: 本文研究了FeSO4•7H2O、硫及黄铜矿适应的Acidithiobacillus ferrooxidans分别与黄铜矿之间的相互作用。通过接触角和Zeta电位来分析细菌及矿物的表面性质，使用热力学方法和extended-DLVO理论来计算和预测细菌与矿物之间的相互作用能，监测2小时内细菌在矿物表面的吸附行为。对比细菌与矿物之间相互作用的差异来揭示细菌在矿物表面吸附的本质，为后续生物浸出创造更加有利的条件。
Abstract: In this paper, interactions between FeSO4•7H2O, sulfur or chalcopyrite adapted Acidithiobacillus ferrooxidans and chalcopyrite were studied. Contact angle and zeta potential experiments were used to analyze the surface properties of bacteria and minerals. Interaction energies between bacteria and minerals were calculated by thermodynamics and extended-DLVO theories; attach-ment behaviors of bacteria to minerals were monitored within two hours. The differences of in-teractions between bacteria and minerals were used to reveal the nature of bacterial attachment, and provide more favorable conditions for bioleaching.
