Environmental Technology 41(12):1514-1519(2020)
A small-scale experiment was conducted to determine the phytoremediation efficiency of two macrophytes, Pistia stratiotes and Eichhornia crassipes, to remove Cr and Cu from prepared metal solutions of different concentrations (2, 4, 6, 8 mg/L) over one month. Both aquatic macrophytes showed different efficiencies for Cr and Cu removal and accumulation. The dry biomass of both macrophytes increased over the period. The average accumulation of Cr in roots and leaves of P. stratiotes was 85 mg and 56 mg, respectively. For Cu, average accumulation was 96 mg and 70 mg, respectively. The average accumulation of Cr in roots and leaves of E. crassipes was 90 mg and 53 mg, respectively. Average accumulation for Cu was 86 mg and 50 mg, respectively. The concentration of metals in the solution significantly decreased from day 1 to day 30. The results of one-way ANOVA showed that removal of Cr was significantly (p<.05) greater in E. crassipes, and removal of Cu was significantly (p<.05) greater in P. stratiotes.
