Abstract

Iron (Fe) and aluminium (Al) contamination due to mining activities has increased considerably and became a serious environmental problem. Phytoremediation is an emerging green technology that uses plants to treat heavy metal contaminated environment. In this study, Scirpus grossus was exposed to synthetic mining wastewater (binary mixture of Fe and Al with a mass ratio of 3:1) to assess its ability to phytoremediate Fe and Al with different treatment concentrations (90 mg/L Fe + 30 mg/L Al - 450 mg/L Fe + 150 mg/L Al). The plants were exposed for 102 d in a subsurface batch system. The results show that the S. grossus accumulated Fe and Al simultaneously in biomass throughout the study. The maximum accumulations of Fe and Al were found on Day 42 in the plant roots (50,277 mg/kg Fe in 450 mg/L Fe + 150 mg/L Al treatment and 7,744 mg/kg Al in 300 mg/L Fe + 100 mg/L Al treatment). The bioaccumulation factor and translocation factor of S. grossus were found to be greater than 1 and less than 1, respectively, for the two metals, indicating that this species is a hyperaccumulator that uses phytostabilization in the phytoremediation of Fe and Al.
