中文摘要: 采用液相还原法制备了维生素B12改性的纳米零价镍,并用来去除溶液中的U(Ⅵ)。探究了纳米零价镍和维生素B12质量比、溶液pH、固液比、溶液中U(Ⅵ)的初始质量浓度以及温度和时间等对溶液中U(Ⅵ)去除的影响。结果表明:在室温(25 ℃)下,维生素B12与纳米零价镍质量比1︰1,溶液pH为5.0,固液比0.3 g/L,反应时间30 min时,U(Ⅵ)的去除率达到98.54%,去除量达到85.36 mg/g。

Abstract:Nano-zero-valent nickel modified by Vitamin B12 was prepared by liquid phase reduction method, which was used to remove uranium U(Ⅵ) from solution. Effects of mass ratio of nanometer zero-valent nickel to Vitamin B12, pH value of solution, ratio of solid to liquid, initial mass concentration of U(Ⅵ) in solution, temperature, and time on removal of U(Ⅵ) in solution were investigated. The results show that removal rate of U(Ⅵ) is 98.54% and removal amount is 85.36 mg/g under the conditions including mass ratio of Vitamin B12 to nano-nickel of 1︰1, pH value of solution of 5.0, ratio of solid to liquid of 0.3 g/L, and reaction time of 30 min at room temperature (25 ℃).
