Abstract

This study reports the removal of ampicillin (AMP) and ibuprofen (IBU) using synthesized Silver nanoparticles (AgNPs) from Thymus fedtschenkoi leaves. This adsorbent was characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray analysis (EDX), Fourier-transform infrared spectroscopy (FTIR), and X-ray powder diffraction (XRD) techniques. The maximum removal efficiency was found at pH=4 (AMP) and pH=6 (IBU), the contact time=30 min, the adsorbent dosage=0.5 g, and drug concentration=30 mg/L. The Langmuir and Freundlich isotherms were investigated to show the Adsorption behavior of AMP and IBU. The Adsorption data followed the Langmuir model with a coefficient of determination (R2)> 0.99. The maximum Adsorption capacity (qmax) was obtained 31.84 and 27.17 mg g-1 for AMP and IBU, respectively. Also, kinetic studies revealed that Adsorption of AMP and IBU were fitted to the pseudo-second-order model with R2 higher than 0.98. AgNPs from Thymus fedtschenkoi can be a promising, inexpensive, and green adsorbent.
