The adsorption capacities for amoxicillin in aqueous solutions were determined to be 613.97 mg/g for MWCNT and 769.23 mg/g for MWCNT@Fe–Cu. Characterization of these materials was carried out using FTIR, BET, TGA, FESEM, EDX, and XRD methods.

Adsorption data adhered to a pseudo-second-order kinetic model and the Langmuir isotherm model provided the best fit. Thermodynamic analysis indicated that the adsorption process was spontaneous and endothermic. The MWCNT@Fe–Cu composite demonstrated remarkable stability after six regeneration cycles, whereas the stability of MWCNT alone diminished over the same period. This enhanced stability is attributed to the Fe–Cu nanoparticles, which prevent agglomeration in aqueous environments.

The structural and textural features were examined through spectroscopic and analytical techniques. The XRD analysis indicated broadening of diffraction peaks and a shift towards higher 2-theta values in the metal-incorporated (M-MCM-41) samples, confirming the successful integration of metal atoms into the MCM-41 framework; it also highlighted the preservation of a hexagonal structure with reasonable regularity, emphasizing the influence of metal incorporation on the mesoporous architecture of MCM-41.
