Sažetak
The aim of this study was to investigate the adsorptive removal of amoxicillin (AMX) from aqueous solutions using H2SO4-activated carbon produced from hazelnut shells (AC-HS). Characterisation of the AC-HS was performed by N2 adsorption and desorption isotherms, scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR) and pHpzc. A batch technique was used for the investigation of AMX adsorption on AC-HS and the concentration of AMX was monitored by UHPLC. The experimental adsorption data were modelled using appropriate kinetic (pseudo-first order, pseudo-second order and Elovich) and isotherm (Freundlich and Langmuir) models. The maximum adsorption capacity of AMX onto AC-HS was 10.18 mg/g. AMX adsorption onto AC-HS increased from 77 to 87% with the increase of temperature from 25 to 45 °C. Overall, the obtained results indicate that waste lignocellulosic material (i.e. hazelnut shells) could be a promising non-hazardous adsorbent, which can be used for the removal of AMX from water.
