摘要
采用同步液相法制备纳米Fe/Ni双金属来去除溶液中的U(Ⅵ),通过BET、SEM等方法对双金属材料进行表征分析,用批试验法研究n(Fe)/n(Ni)比、pH、初始铀浓度、反应时间和温度对去除U(Ⅵ)的影响。结果表明,铁镍双金属体系去除U(Ⅵ)的最佳pH为3.5,反应平衡时间为30min,25℃时的饱和吸附量为161.91mg/g。
Nanoscale Fe/Ni bimetal was prepared by synchronous liquid phase method to remove U(VI) from aqueous solution. Nanoscale Fe/Ni bimetal was characterized by BET and SEM. Effects of n(Fe)/n(Ni), p H value, initial U(VI) concentration, adsorption time, and adsorption temperature on remove of U(VI) were investigated by batch test method. The results show that adsorption capacity is 161.91 mg/g at pH=3.5, adsorption time of 30 min, and adsorption temperature of 25℃.
