The study investigated the biosorption potentials of Eichhornia crassipes, commonly known as water hyacinth. The biosorption efficacy of Eichhornia crassipes showed that the dosage factor recorded its highest adsorption by the root at 3 g (99.80±0.00%) by the root at 1 g.  At pH 8, cadmium had maximum adsorption (96.85±0.01%) at pH of 4. Chromium had the highest adsorption value in temperature (98.90±0.01% at 50°C by the stem) and time (99.81±0.00% at 30 min by the stem).  Lead was the least adsorbed (88.13±0.00%) at temperature 70°C by the root) and chromium for time (89.94±0.00% at 70°C by the root).  In concentration, chromium was the highest adsorbed metal (99.31±0.00% by the stem at 20 mg/L) and lead the least (90.04±0.01%) by the root at 60 mg/L. These results indicate the potentials of the biosorption efficacies of the leaf stem and root of the Eichhornia crassipes plant.
