“…Compared to conventional solid adsorbents such as mesoporous silica materials 10, 11 and activated carbon 12, 13 , MOFs exhibit more virtues such as versatile framework compositions, exposed active sites, tunable pore sizes, and large specific surface areas. MOFs have been demonstrated to be stable and show good adsorption ability for the removal of various pollutants from aqueous solutions such as heavy metal ions 14 , organic dyes 15, 16 , phenols 17 , oil droplets 18 and humic acid 19 . However, to the best of our knowledge, few studies have been reported on the removal of phosphate from water by MOFs via adsorption, because this process not only needs adequate pore size of MOFs but also specific active sites.…”

Although many efforts have been devoted to the adsorptive removal of phosphate from aqueous solutions and eutrophic water, it is still highly desirable to develop novel adsorbents with high adsorption capacities. In this study, Fe-based metal-organic frameworks (MOFs), MIL-101 and NH2-MIL-101, are fabricated through a general facile strategy. Their performance as an adsorbent for phosphate removal is investigated. Experiments are performed to study the effects of various factors on the phosphate adsorption, including adsorbent dosage, contact time and co-existing ions. Both MIL-101(Fe) and NH2-MIL-101(Fe) show highly effective removal of phosphates from aqueous solutions, and the concentration of phosphates decrease sharply from the initial 0.60 mg·L−1 to 0.045 and 0.032 mg·L−1, respectively, within just 30 min of exposure. The adsorption kinetics and adsorption isotherms reveal that NH2-MIL-101(Fe) has higher adsorption capacity than MIL-101(Fe) possibly due to the amine group. Furthermore, the Fe-based MOFs also exhibit a high selectivity towards phosphate over other anions such as chloride, bromide, nitrate and sulfate. Particularly, the prepared Fe-based MIL-101 materials are also capable of adsorbing phosphate in an actual eutrophic water sample and display better removal effect.

“…In particular, several MOFs have been evaluated such as HKUST-1, MIL-series MOFs and UiOseries MOFs. These MOFs can remove pollutants from water via adsorption, including halogens (Zhao et al, 2014), heavy metals (Ke et al, 2011), toxic dyes (Li et al, 2013a), herbicides (Jung et al, 2013), oils (Lin et al, 2014a), and pharmaceuticals (Jiang et al, 2013a). Some MOFs can even exhibit higher adsorption capacity than conventional adsorbents such as activated carbons (Lin et al, 2014a).…”

To investigate effects of modification of MOFs on removal of acid dyes via adsorption and photodegradation, zirconium-based MOF, UiO-66, and its derivatives were synthesized. UiO-66 derivatives were prepared by using amine (NH2)-containing ligand and incorporating carbon nanotubes (CNTs) and reduced graphene oxide (RGO). During the synthesis UiO-66-NH2, UiO-66-CNT and UiO-66-RGO, were obtained, respectively. While UiO-66-NH2 showed the enhanced adsorption capacity for acid dyes owing to the electrostatic attraction, CNTs were found to be the most effective addition to enhance the adsorption of acid dyes. However, the addition of RGO in UiO-66 (to form UiO-66-RGO) exhibited the highest removal efficiency via photodegradation compared to UiO-66 and other derivatives probably attributed to its unique layered morphology. The presence of NH2, CNTs and RGO not only significantly improved the adsorption capacity for acid dyes but also enabled these UiO-66 derivatives to exhibit photocatalytic activity under visible light irradiation.

“…MOFs can exhibit ultrahigh porosity and high thermal and chemical stability and have been altered for use in various adsorptionrelated areas [43]. Recently, a number of researchers started to investigate the capability of MOFs to remove compounds including removal of metal ions [44][45][46] and toxic dyes [47,48] in aqueous environment. These studies unveiled the fact that several types of MOFs can remain intact in aqueous solutions and show exceptional capacities to remove pollutants from water compared to traditional adsorbents.…”

Ce-1,1 -biphenyl-4,4 -dicarboxylic acid (Ce-bpdc), a novel type of metal organic framework, was synthesized and applied to remove excessive fluoride from water. The structure and morphology of Ce-bpdc were measured by X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy. The effects, such as saturated adsorption capacity, HCO 3 − , and pH, were investigated. The optimal pH value for fluoride adsorption was the range from 5 to 6. The coexisting bicarbonate anions have a little influence on fluoride removal. The fluoride adsorption over the Ce-bpdc adsorbent could reach its equilibrium in about 20 min. The Ce-bpdc coordination complex exhibited high binding capacity for fluoride ions. The maximum adsorption capacity calculated from Langmuir model was high up to 45.5 mg/g at 298 K (pH = 7.0) and the removal efficiency was greater than 80%. In order to investigate the mechanism of fluoride removal, various adsorption isotherms such as Langmuir and Freundlich were fitted. The experimental data revealed that the Langmuir isotherm gave a more satisfactory fit for fluoride removal. Finally, the tested results of ground water samples from three places, Yuefang, Jiangji, and Sanyi which exhibited high removal efficiency, also demonstrate the potential utility of the Ce-bpdc as an effective adsorbent.
