“…[22] Therefore, it is indispensable to remove pollutants (such as XO and TC) from aqueous environments. Also, previous studies [20][21]23] have reported the cases of photocatalytic removal of antibiotics and acid dyes over MOFs, which indicated MOFs have potential adsorption performance.…”

The constructing of efficient photocatalysts for environmental remediation has attracted a great deal of attention in recent years. In this paper, Cr /UiO‐66‐NH2 was synthesized by the chromium acetylacetone grafted on UiO‐66‐NH2 directly and UiO‐66‐NH2‐SA‐Cr (anchored on the Schiff base UiO‐66‐NH2‐SA with chemical bonds) was prepared by post‐synthesis method, which both provided such support in degrading tetracycline (TC) and xylenol orange (XO) under visible light. Compared with UiO‐66‐NH2 and Cr /UiO‐66‐NH2, the photocatalytic experiments indicated that UiO‐66‐NH2‐SA‐Cr possessed significant enhanced photocatalytic activity, with 76.5 % of tetracycline (TC) and 71.5 % of xylenol orange (XO) being removed under the optimization of experimental conditions. The enhanced photocatalytic activity of UiO‐66‐NH2‐SA‐Cr could be attributed to the obvious decrease in the band gap, which could enhance the capacity of visible‐light absorption, and the presence of catalytic sites on the Chromium Schiff base complex was also a key factor for the photocatalytic performance, which could achieve high‐efficiency catalytic activity. Furthermore, these materials also exhibited a good recyclability with almost unchanged degradation efficiency after five recycling tests. Above these indicated that these materials mentioned had great potential in the field of wastewater treatment and antibiotic contaminant.

“…Lin et al [177] synthesized UiO-66, NH2-UiO-66, GO/UiO-66, and CNT/UiO-66 to investigate the adsorption of two acid dyes including AO7 and AY17 from the aquatic environment. For AO7 adsorption, the maximum capacity obtained was 42.6, 55, 80.6, and 66.198 mg/g for UiO-66, NH2-UiO-66, CNT/UiO-66, and GO/UiO-66, respectively.…”

“…At the GO content of 25% (w/w), GO sheets would cover the MOF structure and hinder dye adsorption on the active surface sites of MOF, resulting in a drop in the adsorption capacity.

The adsorptive removal of dyes from industrial wastewater using commercially available adsorbents is not significantly efficient. Metal–organic frameworks (MOFs) offer outstanding properties which can boost the separation performance over current commercial adsorbents and hence, these materials represent a milestone in improving treatment methods for dye removal from water. Accordingly, in this paper, the recent studies in the modification of MOF structures in dye removal from the aquatic environment have been discussed. This study aims to elaborate on the synthetic strategies applied to improve the adsorption efficiency and to discuss the major adsorption mechanisms as well as the most influential parameters in the adsorptive removal of dyes using MOFs. More particularly, the advanced separation performance of MOF-based adsorbents will be comprehensively explained. The introduction of various functional groups and nanomaterials, such as amine functional groups, magnetic nanoparticles, and carbon-based materials such as graphene oxide and CNT, onto the MOFs can alter the removal efficiency of MOF-based adsorbents through enhancing the water stability, dispersion in water, interactions between the MOF structure and the contaminant, and the adsorption capacity. Finally, we summarize the challenges experienced by MOF-based materials for dye removal from water and propose future research outlooks to be considered.

Water is a very valuable natural resource. As the demand for water increases the presence of emerging contaminants in wastewater has become a growing concern. This is particularly true when one considers direct reuse of wastewater. Obtaining sufficient removal of emerging contaminants will require determining the level of removal for the various unit operations in the wastewater treatment process. Membrane bioreactors are attractive as they combine an activated sludge process with a membrane separation step. They are frequently used in a wastewater treatment process and can operate at higher solid loadings than conventional activated sludge processes. Determining the level of removal of emerging contaminants in the membrane bioreactor step is, therefore, of great interest. Removal of emerging contaminants could be by adsorption onto the biomass or membrane surface, biotransformation, size exclusion by the membrane, or volatilization. Given the fact that most emerging contaminants are low molecule weight non-volatile compounds, the latter two methods of removal are usually unimportant. However, biotransformation and adsorption onto the biomass are important mechanisms of removal. It will be important to determine if the microorganisms present at given treatment facility are able to remove ECs present in the wastewater.
