“…To answer this problem, the addition of inorganic materials with hydrophilic characteristics in their structures such as clays [141,142], mesoporous silica [143], zeolite [144] and MOFs [145,146] to form a hybrid membrane or MMM is attractive since it will provide good antifouling properties.…”

The accumulation of pollutants in water is dangerous for the environment and human lives. Some of them are considered as persistent organic pollutants (POPs) that cannot be eliminated from wastewater effluent. Thus, many researchers have devoted their efforts to improving the existing technology or providing an alternative strategy to solve this environmental problem. One of the attractive materials for this purpose are metal-organic frameworks (MOFs) due to their superior high surface area, high porosity, and the tunable features of their structures and function. This review provides an up-to-date and comprehensive description of MOFs and their crucial role as adsorbent, catalyst, and membrane in wastewater treatment. This study also highlighted several strategies to improve their capability to remove pollutants from water effluent.

Mixed matrix membranes are considered as a novel generation of membranes that have favorable separation and stability properties of inorganic and polymeric membranes at the same time. In this study, the effects of presence of clay nanoparticles (CNs) on the enhancement of properties and performance of PVC nanofiltration membranes were investigated. FTIR, AFM, XRD, EDS, and FESEM analyses were used to evaluate the mixed matrix membranes. Significant improvements in the membrane hydrophilicity, porosity, permeation flux, and rejection were observed by incorporating CNs. The highest rejection of 94.8% was obtained with mixed matrix membranes containing 2 wt% of CNs. The permeation flux of this membrane was enhanced by 75% relative to the neat membrane.

“…Finally, the MOF-5 membrane was activated at 100 °C for 6 h. The produced membrane exhibited higher pervaporation flux for pure component and separation factor for binary mixtures up to 27.7 for toluene/TIPB. The electrochemical deposition (EDS) method was proposed in many works to overcome inhomogeneity of MOF formation by in situ and secondary growth methods (Jacob et al,2020). The MOF membrane was generated via the EDS method through anodic dissolution and reductive deprotonation (Rahimi et al,2021).…”
