Using Iron-copper Nanocomposites Prepared by Peanut Vine Extracts for the Removal of Pefloxacin and Enrofloxacin from an Aqueous Solution: Isotherms, Kinetics, and Mechanism
Herein, A facile and green approach was employed to fabricate iron-copper nanocomposites (ICNCs) using peanut vine extracts, and the ICNCs were used for the removal of pefloxacin (PFX) and enrofloxacin (ENR) from aqueous solution. Following this, ICNCs were comprehensively characterized by BET, XPS, SEM, FT-IR and EDS. The equilibrium adsorption data of PFX and ENR on ICNCs were well described by Langmuir and Sips isotherm models, and thermodynamics parameters revealed the spontaneous and endothermic nature of PFX and ENR adsorption processes. Kinetic data were best fitted by pseudo-second-order model. Hydrogen bonding, π-π and n-π electron-donor-acceptor interaction, complexation and electrostatic interaction were the main forces in adsorption processes of ICNCs. The maximum monolayer adsorption capacities of ICNCs for PFX and ENR were 240.70 and 195.97 mg/g at 298 K, respectively, indicating that ICNCs is a promising adsorbent for PFX or ENR removal in wastewater treatment.
