Removal of heavy metals by water hyacinth, Eichhornia crassipes Solms-Laub, was examined with two heavy metals Cd, Cu under laboratory conditions. Cd in culture solution was reducd to 0.116, 0.873, 2.015, 3.755 and 4,747 mg/L from 1, 2, 3, 4 and 5 mg/L for 24 hrs, after cultivating of water hyacinth...

Removal of heavy metals by water hyacinth, Eichhornia crassipes Solms-Laub, was examined with two heavy metals Cd, Cu under laboratory conditions. Cd in culture solution was reducd to 0.116, 0.873, 2.015, 3.755 and 4,747 mg/L from 1, 2, 3, 4 and 5 mg/L for 24 hrs, after cultivating of water hyacinth respectively And, Cu was reduced to 0.086, 0.600, 2.174, 3.473, and 4.365 mg/L from 1, 2, 3, 4, and 5 mg/L for 24 hrs, after the cultivation, respectively. Cu was removed faster than Cd nd airating cultivation was effected higher than fixing cultivation. Removal effect of heavy metals by water hyacinth was higher in low a heavy metal cocentration than in high concentration
