摘　　要：研究了用杨木炭制备载铁生物炭(FeBC)并用于从含铀矿井水中吸附铀,通过静态试验考察了溶液pH、初始铀质量浓度、反应时间、固液质量体积比、反应温度对FeBC吸附去除铀的影响;模拟某含铀矿井水化学组成,通过动态试验考察了FeBC对铀的吸附量及吸附性能。结果表明:在初始铀质量浓度20 mg/L、固液质量体积比0.1 g/100 mL、反应时间60 min、反应温度25℃条件下,FeBC对铀的吸附效果较好;在吸附原液铀质量浓度2 mg/L、流量5 mL/min条件下,用50 g FeBC吸附铀,铀吸附量为6.8 mg/g,饱和吸附量为7.2 mg/g,吸附性能良好。The preparation of iron-loaded biocharbon(FeBC)using poplar wood charcoal and using the FeBC to treat uranium-contained wastewater were studied.The effects of wastewater pH,initial uranium mass concentration,reaction time,solid mass-to-liquid volume ratio,reaction temperature on adsorption of uranium were examined.By simulating well water composition and dynamic tests,adsorption capacity and performance of FeBC for uranium were researched.The results show that the FeBC has good adsorption effect for uranium under the conditions of initial uranium concentration of 20 mg/L,solid mass-to-liquid volume ratio of 1 g/L,contact reaction time of 60 min and temperature of 25℃.Under the conditions of initial uranium concentration of 2 mg/L,flow of 5 mL/min and FeBC mass of 50 g,the FeBC adsorption for uranium is 6.8 mg/g,and the saturation capacity is 7.2 mg/g,adsorption performance is good.
