Synthesis of zinc-carboxylate metal-organic frameworks for the removal of emerging drug contaminant (amodiaquine) from aqueous solution

Nanomaterials for the Treatment of Heavy Metal Contaminated Water

“…Owalude coworkers analyzed the sorption of Pb 2+ , Cd 2+ , Zn 2+ , Cu 2+ and Hg 2+ metals ions from their respective aqueous solution by treating formaldehyde (HCHO) and pyridine-fabricated with bean husks as the bio-sorbents. The adsorptive potential of the modified formaldehyde with bean husks (mg/g) was determined to be 5.0 mg/g; 3.63 mg/g; Zn 2+ mg/g, 2.18 mg/g; 1.82 mg/g; 1.58 mg/g, while the pyridine-modified bean husk was analyzed to be 6.92; 3.63; 2.64; 2.48; 1.91 mg/g respectively [ 93 ]. Moreover, it was concluded while using isotherm models and q max determined that the adsorptive potential of these metal ions were in the order of Pb 2+ >Cd 2+ >Zn 2+ >Hg 2+ >Cu 2+ for formaldehyde-modified bean husks and Hg 2+ >Cd 2+ >Pb 2+ >Zn 2+ >Cu 2+ for pyridine-modified bean husks [ 93 ].…”

Investigation of Curcumin Absorption by Aqueous Solution using Magnetic Metal-organic Framework Nanocomposite NiFe 2 O 4 @SiO 2 @HKUST-1

“…There are several different kinetic models used in this study to better understand the experimental data of the process of absorption of curcumin solution by magnetic metal-organic framework nanocomposite synthesized from quasi-first and second-order kinetics and intramolecular penetration to quantify the quantitative absorption kinetics. The quasi-first-order model occurs with an equation of 6 expressing penetration into the single layer, and the changes in adsorption value over time are proportional to the number of unoccupied adsorbent sites [38][39][40].…”

Rising profile on the use of metal–organic frameworks (MOFs) for the removal of heavy metals from the environment: an overview

“…A serious factor limiting the use of this method is the lack of the formation of crystals of big sizes needed to obtain good structural data. Environmentally friendly solvent-free/mechanochemical synthetic methods have been reported by our group for the preparation of metal-organic frameworks and coordination polymers Tella et al , 2015Tella et al , 2017bTella et al , 2017cTella et al , 2018. Also of recent, the geometry of the SBU has been determined to be influenced not only the structure of the ligand and type of metal used, but also the ratio of the metal to ligand, the solvent, and the source of anions to balance the charge of the metal ion (Collins et al 2008).…”
