Abstract
Aquatic plants (Eichornia crassipes, Pistia stratiotes and Salvinia cucullata)
were grown in a nutrient solution in the presence of Cd ion (0,2 mg/L). Analysis
were performed to established whether there was a removal of Cd in solution
and there was accumulation of Cd in the roots and shoots of the plants.
Analysis of Cd concentrations in water was performed everyday and at the end
of the experiment the shoot and root of the plants was harvested. The results
showed that Cd concentrations in all solutions declined until tenth day.
Eichornia crassipes could remove Cd in solution completely by six days. While
Pistia stratiotes and Salvinia cucullata of Cd removal rate were 93,5 % and 77,4
%, respectively. Root to shoot concentration ratio of Cd was 36 for Eichornia
crassipes and 10 for Pistia stratiotes.
