Conference paper


Nowadays the research for wastewater from industrial effluents focuses removal of heavy metals by using agro-waste as adsorbents. Bioremediation of heavy metal ions using agro-waste is known as bio-sorption. This research checks the efficiency of the Banana peel (Musa sapientum) and potato (Solanum tuberosum) peel biomass as an agro-waste. Lead metal removal experimented under controlled experimentation in batch processes with a single metal solution. From the experimentation, results show that metal sorption increases when the equilibrium metal concentration rises but it decreases the removal efficiency of bio-sorbent. The results shows 90.99% removals of metal ions with the use of potato peels as bioadsorbant at lowest concentration of 2 mg/l. The plot of bio-sorption equilibrium isotherms were drown for metal uptake capacity (q) against residual metal concentrations (Cf) present in solution. Langmuir and Freundlich models were used to represent the (q) versus (Cf) sorption isotherm relationship. The values of separation factor were considered in-between zero and one to indicate favorable sorption of tested Lead metal on the bio-sorbent. The attractive sorbtion result was observed by the use of non-living biomass of potato (Solanum tuberosum) in efficient removal of lead at low concentrations.
