Abstract

The preparation of biochar composite materials for heavy metal removal is currently a research hotspot. A biochar composite (nZVI@BC) was synthesized from zero-valent iron nanoparticles (nZVI) and rice husk biochar (BC) by ball milling method in this study. SEM and XRD techniques were employed to examine the composite materials’ phases and microstructural features. The adsorption capacity of nZVI@BC prepared by ball milling was 1.65 times that of rice husk biochar. The adsorption kinetic studies revealed that the composite material’s uptake of Cu2⁺ aligned with a pseudo-second-order kinetic model. This finding suggests that the primary mechanism driving the removal of Cu2⁺ was chemisorption, a process involving chemical interactions between the adsorbent and the metal ions. Soil incubation experiments revealed that introducing the composite material had multiple beneficial effects on acidic soil, decreasing Cu concentration, increasing the pH level, and increasing the electrical conductivity, thereby enhancing the overall physicochemical characteristics of the soil. From a cost-effectiveness standpoint, applying nZVI@BC at 5% concentration proved to be particularly effective in improving the physicochemical properties of acidic soil.
