“…Recently, metal-organic frameworks (MOFs), a class of porous material with inherent large surface areas, uniform but tunable cavities, tailorable chemistry and useful physical and chemical properties, have obtained broad and comprehensive applications than activated carbon and zeolites (Dehghankar et al, 2021). Although MOFs have been explored for a wide range of applications in catalysis, gas storage, chemical sensing, and drug delivery (Zhuang et al, 2014;Yang and Xu, 2017;Xie et at., 2018), there have been only a few reports on using MOFs for removal of heavy metals from wastewater (Efome et al, 2018;Asghar et al, 2021). Among all the reported MOFs, Cu-based MOFs are attractive because the high stability and earthabundance of the Cu element makes them ideal sacrificial templates to prepare adsorbent with high surface area and porosity.…”

The biggest challenge of this century is the generation of wastewater which is released to the environment due to industrial expansion. Industrial development has caused the release of various pollutants including heavy metals such as Cd, Pb, and Cr into the environment. In this study, copper diphenylamine metal-organic framework (Cu-DPA MOF) has been synthesized via hydrothermal method and its adsorption capacity toward the removal of heavy metals from wastewater was examined. The removal efficiency of heavy metals by Cu-DPA MOF was tested at optimized adsorption parameters such as optimal adsorbent dosage, pH, initial metals concentration, and adsorption time. The heavy metals concentration in the wastewater before treated with the as-synthesized MOF was determined to be 0.3027, 0.0098, and 0.1021 mg/L for Cr, Cd, and Pb, respectively. The corresponding concentrations of heavy metals in wastewater were reduced to 0.0015, 0.00024, and 0.00016 mg/L when treated with the as-synthesized MOF. As a result, a maximum removal efficiency of 97.6%, 99.5%, and 99.5% was achieved for Cd, Cr, and Pb metals, respectively. This is possibly due to the high porous nature and huge surface area of the as-synthesized MOF. The adsorption data were best fitted with Freundlich isotherm throughout this study. The study sheds light on the design of adsorbents with high removal efficiency of pollutants found in the environment.

“…In general, the technologies that have been used for the removal of heavy metals are based on physicochemical and biological methods. Whilst, at present, biological methods are considered because of their sustainability and cost-effectiveness [ 7 , 8 ], physicochemical methods such as adsorption, membrane filtration and flotation are still more widely used across the world [ 9 , 10 , 11 ]. Compared with other technologies used in the removal of hazardous pollutants from water, adsorption technology has attracted more attention due to its easy design, low cost and the recyclability of adsorbents [ 12 , 13 , 14 ].…”

A Brief Review of Recent Results in Arsenic Adsorption Process from Aquatic Environments by Metal-Organic Frameworks: Classification Based on Kinetics, Isotherms and Thermodynamics Behaviors

In nature, arsenic, a metalloid found in soil, is one of the most dangerous elements that can be combined with heavy metals. Industrial wastewater containing heavy metals is considered one of the most dangerous environmental pollutants, especially for microorganisms and human health. An overabundance of heavy metals primarily leads to disturbances in the fundamental reactions and synthesis of essential macromolecules in living organisms. Among these contaminants, the presence of arsenic in the aquatic environment has always been a global concern. As (V) and As (III) are the two most common oxidation states of inorganic arsenic ions. This research concentrates on the kinetics, isotherms, and thermodynamics of metal-organic frameworks (MOFs), which have been applied for arsenic ions uptake from aqueous solutions. This review provides an overview of the current capabilities and properties of MOFs used for arsenic removal, focusing on its kinetics and isotherms of adsorption, as well as its thermodynamic behavior in water and wastewater.
