In the present study, a novel magnetically separable activated carbon nanohybrid (MnFe2O4@BAC) was produced by using the microwave-assisted chemical co-precipitation method of industrially processed black cumin solid waste-derived activated carbon (BAC) and manganese ferrite nanoparticles (MnFe2O4). It was characterized by VSM, XRD, Raman, BET, SEM-EDX, FTIR, Boehm titration, and pHPZC analysis techniques. Spinel MnFe2O4 nanoparticles significantly affected the pore properties of BAC. MnFe2O4@BAC exhibited a saturation magnetization property of 14.6 emu/g. Also, the optimal sorption conditions of oxytetracycline (OTC), which was chosen as a model to test the antibiotic sorption ability from water, were decided according to the optimum influences of operational variables. The kinetic and isotherm results best described the pseudo-second-order and Langmuir models, respectively. The maximum OTC sorption ability of MnFe2O4@BAC was determined as 591.7 mg/g under specified optimal sorption conditions. Thermodynamic parameters were calculated to show that the sorption is spontaneous volitional and endothermic. The spent MnFe2O4@BAC was accumulated after sorption using an external magnetic field for subsequent reuse and showed excellent reusability stability. © 2024 Elsevier Ltdeninfo:eu-repo/semantics/closedAccessActivated carbonBlack cumin wasteManganese ferrite nanohybridOxytetracycline antibioticReusabilitySorptionArticle123WOS:0012262937000012-s2.0-8518985858110.1016/j.jece.2024.112641N/AN/A
