Synergistic adsorption of Sb(V) using wet ball milling of manganese slag supported by biochar

This study used wet ball milling to synthesize ball-milled biochar-based manganese slag composites (QBM) with a 1:1ratio of biochar to manganese slag. The goal was to improve the adsorption efficiency of Sb(V) and the resource utilization of waste manganese slag. Herein, physicochemical properties, leaching toxicity, and Sb(V) adsorption properties of the composite materials were discussed. The composite materials exhibited a reduction of 9.7%, 63.9%, 15.2%, and 70.9% in pH value, conductivity, cation exchange capacity, and particle size, respectively, after being wet ball milled at room temperature for 8hours with a solid-liquid ratio of 1:6 and a rotation speed of 150r/min. Zeta potential significantly increased (P © 2024 Chinese Society for Environmental Sciences. All rights reserved.
