Abstract
Increasing population and rapid industrialization increases effluent discharge into aquatic ecosystems. Heavy metals are major toxicants found in industrial effluents. Dried and powdered biomass of Canna indica including root, shoot and leaves has been used for the removal of Pb(II) metal ions from aqueous solution. The adsorption capacity of dry biomass was determined as a function of pH, contact time, initial concentration, doses of biomass & temperature. The results obtained shows that the pH has marked effect on metal ions uptake. The maximum adsorption observed at pH 6. After contact time of 80 minutes the percent removal of Pb(II) ion was 72.80, 80.45 and 93.75 on root, shoot and leaf respectively with initial concentration of 20mg/l. The effective dose of metal ion was 1g each of the root, shoot and leaf. The adsorption of Pb(II) was tested by Fruendlich adsorption isotherm and is inversely related to the temperature. Result shows that the leaves are more efficient media for removal of Pb(II) as compared to root & shoot. The study can be used for the development of an efficient, clean and cheap technology for effluent treatment.
