摘　　要：采用离子交换法制备出了葡萄糖酸根插层的类水滑石,并对其进行了XRD、FT-IR、TG等表征。将这一新型吸附剂应用于吸附溶液中的硼,并对影响其吸附容量的条件进行了实验研究。结果表明,该吸附剂比MgAl-NO3--LDH对硼有较高的吸附容量,且吸附容量随着接触时间的延长而增大,随硼浓度的增大而增大,随着pH的增加而增大,随着氯离子浓度的增大而减小。Glucosate-intercalated hydrotalcite was prepared by ion-exchange method more easily.The resulting adsorbent was characterized by XRD,FT-IR and TG.This new kind of adsorbent was applied to adsorb boron in the solution,and the influencing conditions on its adsorption capacity were investigated.The experimental results showed that the adsorbent obtained held a higher adsorption capacity for boron than that of the precursor.Meanwhile,the adsorption capacity increased with increasing the contact time,boron concentration and the pH,while decreased with increasing the chloride concentration.
