“…The results of these studies are in agreement with the chemisorption mechanism significant in the rate-limiting step in the adsorption of target azo dye pollutants onto MOFs materials. This is due to valence forces through sharing or exchange of electrons between sorbent and sorbate (Adeyemo et al, 2012). However, a few MOFs have deviated from this kinetic mechanism, such as CR adsorption onto TMU-100(Fe), where the kinetic data fitted the first-order Langergren rate equation (Masoomi et al, 2015) well.…”

“…[19] Various water-stable MOFs (for example, zeolitic imidazolate frameworks (ZIFs), MILs, and Zr 6 -based MOFs) have been demonstrated to be new candidate materials for water purification. The well-known plasticizer dimethyl phthalate (DMP) is an endocrine disruptor that can cause serious damaging effects on the reproductive system and development of humans.…”

Three aluminum compounds, namely alumina, aluminum hydroxide, and boehmite, are probed as the metal sources for the hydrothermal synthesis of a typical metal-organic framework MIL-53(Al). The process exhibits enhanced synthetic efficiency without the generation of strongly acidic byproducts. The time-course monitoring of conversion from different aluminum sources into MIL-53(Al) is achieved by multiple characterization that reveals a similar but differentiated crystallinity, porosity, and morphology relative to typical MIL-53(Al) prepared from water-soluble aluminum salts. Moreover, the prepared MIL-53(Al) constructed with the three insoluble aluminum sources exhibit an improved thermal stability of up to nearly 600 °C and enhanced yields. Alumina and boehmite are more preferable than aluminum hydroxide in terms of product porosity, yield, and reaction time. The adsorption performances of a typical environmental endocrine disruptor, dimethyl phthalate, on the prepared MIL-53(Al) samples are also investigated. The improved structural stability of MIL-53(Al) prepared from these alternative aluminum sources enables double-enhanced adsorption performance (up to 206 mg g(-1)) relative to the conventionally obtained MIL-53(Al).

“…Wastewater produced in many industrial processes often contains toxic organic dyes not amenable to direct biological treatment [1]. There are more than 100 000 commercially available dyes, with annually over 700000 tons production which are discharged in wastewater during the dyeing process [2].…”
