Adsorption behavior of methylene blue on Fe3O4-embedded hybrid magnetic metal–organic framework

Selective Adsorption of Aqueous Diclofenac Sodium, Naproxen Sodium, and Ibuprofen Using a Stable Fe3O4–FeBTC Metal–Organic Framework

“…In this work, we used non-functionalized magnetite nanoparticles. It has been proven that simple incorporation (non-functionalized in situ) is a fast and efficient way to obtain magnetic materials composites Fe 3 O 4 –MOFs [ 29 ] with good dispersion and synergy [ 20 , 30 ]. A significant advantage of not functionalizing the magnetite lies in preserving the magnetic properties since they are crucial in the material’s recyclability.…”

“…For the adsorption tests, 3 mg of adsorbent was added to 50 mL of the initial concentration of the drug (50 ppm for DCF, 20 ppm for NS, and 15 ppm for IB) at pH values of 4.5 (DCF), 5.6 (NS), and 3.5 (IB) and a temperature of 303 K. After, aliquots were taken at certain adsorption times (10,15,30,60,120,240, and 360 min). They were analyzed in the UV-vis spectrometer.…”

Poly(butyl methacrylate)‐grafted alginate/Fe3O4 nanocomposite: Synthesis and its application for removal of dyes

“…This study also involved acquisition of adsorption isotherms of PBMA-gft-Alg/Fe 3 O 4 nanocomposite for MG and MB at a temperature of 50 C. Data analysis was carried out with Langmuir, Freundlich, Sips, and Temkin equations as shown in Figure 10a-d, respectively. [66] Equations (3)-(6) represent the Langmuir, Freundlich, Sips, and Temkin isotherm equations, respectively. The adsorption isotherms were modeled by these Equations.…”

Ternary metal oxide embedded carbon derived from metal organic frameworks for adsorption of methylene blue and acid red 73

“…Organic dyes, as introduced by painting, textile, electroplating, leather or paper industrial wastewater, are emerging as important aqueous pollutants, posing threat to the health of aquatic organisms and human being due to their solubility, toxicity, possible carcinogenic effects as well as interference of photosynthesis through absorption to incident light (Adeyemo et al, 2012;Katheresan et al, 2018;Kaur et al, 2019;Lellis et al, 2019). For example, methylene blue (MB), a common cationic dye, was found to cause eye irritation, vomiting, mental disorder, and has even been identified as a mutagen and carcinogen (Yao et al, 2010;Zhao et al, 2015;Xu et al, 2016). Common treatment techniques for dye wastewater include biological treatment, adsorption, coagulation, advanced oxidation, membrane filtration and photocatalysis (Gupta, 2009;Yagub et al, 2014;Ahmad et al, 2015).…”
