摘要

This study examines the synergistic effect of titanium oxide and aluminum powder on cadmium cementation from aqueous solutions, focusing on the role of oxygen. Individually, titanium oxide and aluminum powder removed less than 10 and 20 pct of cadmium, respectively, with oxygen having little impact. However, their combination significantly enhanced cadmium removal, achieving 80 pct in oxygenated conditions and 63 pct in its absence. The presence of oxygen initially increases the formation of cadmium sulfate and hydroxide compounds, improving removal efficiency, but later facilitates its dissolution, leading to increased cadmium concentrations. At pH around 6, changes in oxidation-reduction potential (ORP) further influence cadmium stability. These findings underscore the importance of oxygen, pH, and ORP control in optimizing cadmium cementation, contributing to improved hydrometallurgical applications for metal recovery and environmental remediation.
