冶金模式微生物Acidithiobacillus ferrooxidans表面质子吸附特性的研究周姗1,栗树珍1,钟慧2,贺治国11. 中南大学资源加工与生物工程学院生物冶金教育部重点实验室2. 中南大学生命科学学院摘 要:为了探究生物冶金过程及矿山酸性废水中的关键微生物Acidithiobacillus ferrooxidans的表面质子吸附机理,该研究通过酸碱滴定,ProtoFit模拟,电泳迁移率测定及傅里叶变换衰减全反射红外光谱法(ATR-FTIR)系统地揭示不同能源(S0,Fe2+,FeS2)和离子强度(0.001~0.1 mol/L NaNO3)对A.ferrooxidans表面性质的影响及参与质子化/去质子化反应的关键官能团.结果表明:三位点的Donnan壳静电模型能较好地适用于分析......
">The present work investigated microbial leaching of zinc from ore using Acidithiobacillus ferrooxidans (ATCC 14859). The ore samples, consisted of 13wt% zinc, were obtained from a gold mine in north-eastern... ferrooxidans can successfully leach zinc by as much as 6 times compared with the control experiment (without Acidithiobacillus ferrooxidans ferrooxidans). The maximum efficiency (92.3%) for microbial......
