“…Glyphosate, N -(phosphonomethyl) glycine, has been extensively utilized as an organophosphorus herbicide all over the world due to its low toxicity, broad-spectrum activity and non-selectivity. 1 However, the massive use of glyphosate has led to the ubiquitous contamination of soil surface and water resources, which seriously threatens human health and the ecological equilibrium. 2 Therefore, its detection and removal have become the focus of growing attention and interest.…”

“…Nanoadsorbents have been reported as a new generation of adsorbents with higher adsorption capacity, making them more e cient for the adsorption of antibiotics and other emerging pollutants [15,16,18,19,31]. Furthermore, there are numerous nanoadsorbents used to remove antibiotics, including graphene-based nanoadsorbents [33], gold nanoparticles [34], zero-valent iron (ZVI) nanoparticles [35] and titanium dioxide nanoparticles [36]. Filtration and centrifugation methods are used to separate the nonmagnetic adsorbents from an aqueous solution [37].…”

This study aimed to synthesize Fe 3 O 4 @Methylcellulose/3-Aminopropyltrimethoxysilane (Fe 3 O 4 @MC/APTMS) as a new magnetic nano-biocomposite by a facile, fast, and new microwave-assisted method and to be utilized as an adsorbent for tetracycline (TC) removal from aqueous solutions. Fe 3 O 4 @MC/APTMS was characterized by Fourier transform-infrared (FTIR), Field emission scanning electron microscopy (FESEM), Energy dispersive spectroscopy (EDS), Mapping, X-ray diffraction (XRD), Thermal gravimetric analysis (TGA), Brunauer-Emmett-Teller (BET) and vibrating sample magnetometer (VSM). The point of zero charge (pH zpc ) value of the nano-biocomposite was estimated to be 6.8 by the solid addition method.Optimum conditions were obtained in TC concentration: 10 mg L −1 , adsorbent dosage: 80 mg L −1 , contact time: 90 min, and solution pH: 6 with the maximum TC removal of 90% and 65.41% in synthetic and actual samples, respectively. The kinetic and isotherm equations pointed to a pseudosecond order kinetic and Langmuir isotherm optimum tting models. Based on the values of entropy changes (ΔS) (50.04 J/mol k), the enthalpy changes (ΔH) (9.26 kJ/mol), and the negative Gibbs free energy changes (ΔG), the adsorption process was endothermic, random, and spontaneous.The synthesized adsorbent exhibited outstanding properties, including proper removal e ciency of TC, excellent reusability, and simple separation from aqueous media by a magnet. Consequently, it is highly desirable that Fe 3 O 4 @MC/APTMS magnetic nano-biocomposite could be used as a promising adsorbent for TC adsorption from aqueous solutions. HighlightsFe 3 O 4 @MC/APTMSas a new magnetic nano-biocomposite has been synthesized by a new microwave-assisted method and characterized with FESEM, EDS, Mapping, FT-IR, XRD, TGA, BET, and VSM techniques.The maximum removal e ciencies under optimal conditions (pH=6, TC concentration 10 mg L -1 , adsorbent dosage: 80 mg L -1 and contact time: 90 min) for synthetic and actual samples were obtained 90% and 65.41%, respectively.Isotherm, kinetic and thermodynamic study of tetracycline adsorption were investigated.Fe 3 O 4 @MC/APTMS exhibited excellentreusability property up to 5 cycles.
