Removal of cadmium in aqueous solutions using a ball milling–assisted one-pot pyrolyzed iron-biochar composite derived from cotton husk
Original language description
A novel iron biochar composite adsorbent was produced via ball milling assisted one pot pyrolyzed BM nZVI BC 800. Characterization proved that nano zero valent iron was successfully embedded in the newly produced biochar, and the nZVI payload was higher than that of traditional one pot pyrolyzed methods. BM nZVI BC 800 provided a high adsorption performance of cadmium reaching 96,40 mg per gram during batch testing. Alkaline conditions were beneficial for cadmium removal of BM nZVI BC 800. The pseudo second order kinetic model and Langmuir isotherm fitted better, demonstrating that the Cd adsorption on the BM nZVI BC 800 was a chemical and surface process. The intraparticle diffusion controlled the adsorption of BM nZVI BC 800. The physisorption dominated by high specific surface area and mesoporous structure was the primary mechanism in the removal of cadmium, though electrostatic attraction and complexation also played a secondary role in cadmium adsorption.
