Cadmium elimination from wastewater using potato peel biochar modified by ZIF-8 and magnetic nanoparticle
A recyclable and magnetic nanocomposite was fabricated from biochar of potato peel (BPP), MnFe2O4, and ZIF-8 (BET area: 174.92m2/g). The Cd2+ removal using BPP/MnFe2O4@ZIF-8 was maximized at pH 6, a temperature of 45 °C, and a time of 100 min. The capacity of Cd adsorption using BPP, BPP/MnFe2O4, and BPP/MnFe2O4@ZIF-8 was computed to be 33.76, 45.02, and 80.52 mg/g, respectively. The influence of coexistence ions on cadmium elimination by BPP/MnFe2O4@ZIF-8 was explored. Shipbuilding wastewater was treated to an acceptable level using the nanocomposite. The Cd adsorption was endothermic and followed the pseudo-second-order (R2 > 0.98). Therefore, BPP/MnFe2O4@ZIF-8 is an affordable material for treating cadmium.
