The adsorption properties of mesoporous and non-mesoporous UiO-66-NH2 for pollutants in aqueous solutions
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%.
