摘要
通过静态吸附试验,研究了镁铝类水滑石(Mg-Al LDH)对UO_2^(2+)的吸附效果。实验考察了初始pH、吸附剂投加量、吸附时间对Mg-Al LDH吸附U(VI)的影响。试验表明,Mg-Al LDH吸附U(Ⅵ)的最佳p H在6.77,反应在120 min达到平衡,Mg-Al LDH对U(VI)的饱和吸附量为53.4 mg/g。
Through the static adsorption experiment, this paper studied the Mg-Al LDH of UO2 2＋ adsorption effect. The effects of initial pH, adsorbent dosage, adsorption time on adsorption of U（Vl）were investigated. The experiment results indicate that the maximum adsorption occur in 6.77 and the adsorption reach equilibrium within 120 min. And the saturated adsorption of Uranium by Mg-AI LDH is 0.53 mg/g.
