Abstract

In the present research, phytoremediation mechanism of sediment contaminated with pentachlorophenol (PCP) was investigated. Seven species of common aquatic macrophytes were used for remediating PCP contaminated sediment and those plants could significantly accelerate the degradation of PCP in sediments. Among all, Canna indica L. attained 98% of PCP removal, and can be used as efficient alternative plant for remediation. Accumulation of PCP in plant biomass of canna indica L. only made a small contribution to the total removal of PCP. Through the analysis of PCP removal pathways, microbial degradation promoted by aquatic macrophyte was the main mechanism involved in the PCP contaminated sediment phytoremediation.
