中文摘要: 通过溶剂热法制备了CaTiO3,并探究了溶液pH、固液比、U(Ⅵ)初始浓度、反应时间对U(Ⅵ)吸附效果的影响。吸附实验结果表明:在溶液pH为3.5,固液比为0.2 g/L、U(Ⅵ)初始浓度为25 mg/L、反应时间为100 min时,CaTiO3材料对U(Ⅵ)的吸附效果最好,去除率为98.06%,吸附容量为125.19 mg/g。
Abstract:CaTiO3 was prepared by solvothermal method, and effects of pH value of solution, ratio of solid to liquid, U(Ⅵ) initial concentration, and reaction time on adsorption effect of U(Ⅵ) were explored. The results show that CaTiO3 material has the best adsorption effect on U(Ⅵ) with U(Ⅵ) removal rate of 98.06% and adsorption capacity of 125.19 mg/g under the conditions including pH value of solution of 3.5, ratio of solid to liquid of 0.2 g/L, U(Ⅵ) initial concentration of 25 mg/L, and reaction time of 100 min.
