Abstract

The inclusion of dyes in discharges is an important issue appropriate to their ability to negatively impact living things. An innovative, effortless, and highly efficient technique for developing a magnetic Fe₃O₄@Cu₃(BTC)₂ as a sorbent for removal organic molecules from aqueous solution is evaluated for removal of direct blue 80 (DB80) as a case study. The as-synthesized hybrid nanocomposite was investigated using XRD, FTIR, BET, TEM, XPS, and VSM approaches. The novel adsorbents merge the benefits of MOFs with magnetic nanoparticles, with their great capacity, quick removal and simple solid-phase separation, making them effective sorbents for wastewater treatment. The resulting magnetic Fe₃O₄@ Cu₃(BTC)₂ composites have a superior magnetic response (24.16 emu g⁻¹), as well as mechanical stability, which leads to separation quickly in just a few minutes when predominate to an external magnetic field. At an initial dye concentration of 50 mg/L, contact period of 60 min, and adsorbent content of 5 mg, the maximum adsorption efficiency of 97.21 % for Fe₃O₄@Cu₃(BTC)₂ was achieved, compared to 85.11 % for Cu₃(BTC)₂. Kinetic parameters revealed pseudo-second-order, and adsorption was specified by the Langmuir isotherm where q_e (mg/g) = 92.18 and R² = 0.9997. Additionally, the remarkable reusability of the Fe₃O₄@Cu₃(BTC)₂ adsorption agent, which maintains its effectiveness for at least five consecutive cycles. The effects of adsorbent dosage, contacting time, and pH had the greatest influence on DB80 uptake, according to the statistical analysis conducting using response surface methodology (RSM). Fe₃O₄@Cu₃(BTC)₂ exhibit potential for treating DB80 in an environmentally friendly way.

期刊介绍： Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
