(1) Title: The removal of bisphenol A from aqueous solutions by MIL-53(Al) and
mesostructured MIL-53(Al)
Abstract: metal–organic framework MIL-53(Al){Al(OH)[O2C-C6H4-CO2]} and MIL-53(Al)-
F127{Al(OH)[O2C-C6H4-CO2]} were synthesized and used as sorbents to remove bisphenol A (BPA) fromaqueous system. The sorption kinetics data of BPA were found to be in agreement with the pseudo-second-order model. The equilibrium sorption amounts of BPA on MIL-53(Al) and MIL-53(Al)-F127 reached329.2 ± 16.5 and 472.7 ± 23.6 mg g1, respectively, far more than that of commercial activated carbons(ranging from 129.6 to 263.1 mg g1). Both MIL-53(Al) and MIL-53(Al)-F127 could remove BPA fast fromaqueous solutions, and the required contact time to reach equilibrium was approximately 90 min for
MIL-53(Al) and 30 min for MIL-53(Al)-F127, respectively. The optimum pH levels for the removal ofBPA using MIL-53 (Al) and MIL-53(Al)-F127 were 4 and 6 separately. The optimum temperature forthe sorption behavior of BPA on the two sorbents was 20 C. The results performed show that the resulting products, as one kind of MOFs, can be regarded as a new class of sorbents for water treatment andcould find great applications in the fields of environmental water pollution control and resources reuse.

Abstract:Effective deposition of MOFs on “inert” solid surfaces is verychallenging. In this work, we found that polydopamine, whichcan be facilely and tightly formed on any types as well as anyforms of solid surfaces, could be used as effective nucleationcenter for MOFs deposition. Based on this finding, variousMOFs were successfully deposited on nanofibrous polymermembranes, especially the commercially available “inert”ones, affording hierarchically structured porous films.
