Green synthesis of BT-Fe3O4 nanocomposite using Camellia sinensis leaves extract: Characterization, NPEO adsorption experiments,isotherms, and kinetics
Öz
In this study, Black Tea-Fe3O4 (BT-Fe3O4) magnetite nanocomposites was synthesized from extract of black tea (BT-Camellia sinensis) leaves with an eco-friendly method, and used to investigate nonylphenol ethoxylate (NPEO) removal potential from water. The results of the characterization determination studies performed on the adsorbent revealed that the herbal extract obtained from black tea leaves successfully covered the surface of magnetite (Fe3O4) nanoparticles. Batch tests were carried out to define the action of BT-Fe3O4 dose, initial NPEO concentration, pH and contact time on the adsorption attitude of the BT-Fe3O4. Adsorption isotherms and kinetics were described by a Freundlich isotherm model and pseudo-second-order kinetic model. The experimental results showed that maximum adsorption efficiency of NPEO (%73.45) occurred the optimal pH value of 7.0, NPEO concentration of 10 mg/L, BT-Fe3O4 dose of 1g/L, and contact time of 60 minutes. The results of the study have shown that BT-Fe3O4 particles have promising applicability in the removal of NPEO from aqueous media by adsorption method as an environmentally friendly and low-cost alternative adsorbent with rapid separation ability for wastewater treatment.
