摘　　要：以氨基-对苯二甲酸为配体和Zr4+反应制备介孔UiO-66-NH2和非介孔UiO-66-NH2,并对化合物进行表征和分析.研究结果表明,介孔UiO-66-NH2具有明显的介孔孔道;通过对污染物亚甲基蓝、罗丹明B和双氯芬酸钠进行吸附的实验发现,介孔的引入明显增强UiO-66-NH2对水中污染物的吸附性能.在25℃下,充分震荡90 min后,介孔UiO-66-NH2对双氯芬酸钠的吸附率高达99.13%.Mesoporous UiO-66-NH2 and non-mesoporous UiO-66-NH2 were prepared using amino tere-phthalic acid as ligand and Zr4+reaction,and the compounds were characterized and analyzed.The research re-sults show that there are obvious mesoporous channels in the mesoporous UiO-66-NH2..Through the experi-mental study on the adsorption of methylene blue,rhodamine B and diclofenac sodium,it was found that the in-troduction of mesopores significantly enhanced the adsorption performance of UiO-66-NH2 for pollutants in water.Under the condition of full vibration at 25℃,90 min,its adsorption rate of diclofenac sodium was up to 99.13%.
