| Kenaf plants were hydroponically grown in reactor containing toxic metals as Cd, Cu, Cr, Ni and Zn to examine the ability to take up heavy metal. The plants were fertilized using a nutrient solution, which was appropriately adjusted to optimum pH, DO and conductivity. For n hydraulic retention time of 8 days, Cr, Cd, Cu, Ni and Zn were removed up to 90.5, 80.5, 66.1%, 71.1% and 79.4%, and reduced from 2.34 to 0.54 mg $L^{-1}$, 3.37 to 1.07 mg $L^{-1}$, 4.92 to 3.19 mg $L^{-1}$, 6.31 to 4.41 mg $L^{-1}$ and 6.27 to 2.09 mg $L^{-1}$. Especially, accumulation rate of Cr, Cd, Cu, Ni and Zn in the plant were measured up to 347.32, 275.39, 157.52, 50.48 and 211.01 mg DW kg $L^{-1}d^{-1}$, respectively. We considered that Kenaf plants removed Cr, Cd and Zn more effectively than other toxic metals applied. |
