| 摘 要： | 采用自行采集的氧化亚铁硫杆菌(T f)应用于地浸矿山代替双氧水作氧化剂氧化吸附尾液中的Fe2+, 研究了温度、pH 值对其氧化Fe2+的影响。研究结果表明, T f 氧化Fe2+最适宜的温度为30 ℃, 当温度低于7 ℃或高于50 ℃时, 氧化亚铁硫杆菌氧化Fe2+速度很慢;T f 氧化Fe2+最适宜的pH 为2.0～2.5 。

| Abstract: | The effects of temperature and pH on oxidation of Fe2+ were investigated by applying self-collected thiobacillus ferrooxidans(Tf)instead of hydrogen peroxide as oxidant to oxidize and absorb Fe2+ in tailing water.It was found that the most suitable temperature at which Tf oxidizes Fe2+ in tailing water is 30 ℃.When the temperture is lower than 7 ℃or higher than 50 ℃, the Fe2+ oxidation rate is small.The most suitable pH of which Tf oxidizes Fe2+ is 2.0 ～2.5. |
