Abstract

Heavy metal pollution is a global problem that affects both the environment and human health. Microorganisms play an important role in remediation. Most studies on the use of microorganisms for heavy metal remediation focus on single heavy metals. In this study, a strain of Penicillium amphipolaria, XK11 with high resistance to both antimony (Sb III) and cadmium (Cd II) was screened from the mineral slag. The strain also had a high phosphate solubilization capacity. The single-factor adsorption experiment results showed that the initial pH (pH0), adsorption time (T), and initial solution concentration (C0) all affected the adsorption of Sb and Cd by XK11. When the initial pH0 (Cd = 6, Sb = 4) and adsorption time (T = 7 d) were constant, XK11 achieved the maximum removal rate of Cd (45.6%) and Sb (34.6%). These results confirm that XK11 has potential as a biomaterial or remediation of Sb and Cd pollution.
