The applicability of the synthesized Origanum majorana-capped silver nanoparticles for eliminating dyes from aqueous media has been confirmed. Identical techniques including Fourier-transform infrared spectroscopy, Brunauer–Emmett–Teller, energy-dispersive X-ray spectroscopy, X-ray diffraction, transmission electron microscopy and scanning electron microscopy has been utilized to characterize this novel material. The investigation showed the applicability of Origanum majorana-AgNPs as an available, suitable and low-cost adsorbent for proper deletion of ethylparaben, methylparaben and propylparaben dyes from aqueous media. The optimal conditions for the paraben dyes removal were found to be 7, 65 min, 100 mg L–1, and 50 mg for pH, contact time and adsorbent dosage, respectively. To evaluate the mechanism of adsorption, the kinetic of adsorption process followed second-order equation model. The adsorption mechanism was found fit the second-order (k2= 40.0, 20.6 and 30.05 g mg–1 min–1 for methylparaben, ethylparaben and propylparaben dyes and R2= 0.98). After using various isotherm models to fit the experimental equilibrium data with, the adequacy and applicability of Langmuir model has been proven. Thermodynamic parameters of free energy (ΔG), enthalpy (ΔH) and entropy (ΔS) of adsorption were determined using isotherms. The fact that the sorption process was exothermic was the negative value of (ΔG, ΔH and ΔS) which on its own expressed the affinity of Origanum majorana-AgNPs for removal ethylparaben, methylparaben and propylparaben. The maximum monolayer capacity (qmax) was observed to be …
