Application of Live and Non-metabolizing Cells of Aspergillus flavus Strain 44-1 as Biosorbent for the Removal of Lead from Solution

K.H. Kok, M.I.A. Karim, A.B. Ariff and S. Abd-Aziz    

Abstract: Study on the feasibility of using Aspergillus flavus cells as biosorbent to remove lead from solution was carried out using a 500mL shake flask. The effect of metal concentration, biosorbent concentration, temperature and pH on lead adsorption were investigated. The maximum uptake of lead by Aspergillus flavus cells was 144.5 mg lead/g dry cell. The highest uptake of lead by this biosorbent was occurred at pH 4 and temperature 400C.
