Abstract

BIOSORPTION of HEAVY METALS can be an effective process for the removal of heavy metal ions from aqueous solutions. In this study, the removal of Pb (II) and Zn (II) by dead cells of a lignolytic whiterotfungs, Phanerochaete chrysosporium, was investigated. In addition, the effect of pretreatment of P.chrysosporium BIOMASS on BIOSORPTION of Pb (II) and Zn (II) was studied. Pretreated P.CHRYSOSOPORIUM has been used for BIOSORPTION of metals in this study. Here, the ADSORPTION technique has been done in Batch system. The effects of the initial metal ion concentration, initial pH, stirring speed and contact time on BIOSORPTION efficiency were studied. The surface change density of thebiosorbents varied with the pH of the medium and the maximum BIOSORPTION of heavy metal ions on the BIOSORBENTs was obtained between Ph 5 and 6.The BIOSORPTION of Pb (II) and Zn (II) on the BIOSORBENTs increased as the initial concentration of Pb (II) and Zn (II) ions were increased in the medium. BIOSORPTION equilibrium was established about 1 h, the adsorbed heavy metal ion did not significantly change further with time. The maximum heavy metal ions adsorbed was found to be 90 and 63 mg/g dry BIOMASS P.chrysosporium for Pb (II) and Zn (II), respectively.The results indicated that increasing the temperature led to an increase in the ADSORPTION rate. The experimental ADSORPTION data were fitted to the Langmuir and Freundlich ADSORPTION models. The affinity order of heavy metal ions showed Pb (II)>Zn (II). The BIOMASS was regenerated by washing with a 50 mM solution of HCI. The desorption efficiency was as high as 98%. The results suggested that P.chrysosporium could be used as a BIOSORBENT for an efficient removal of heacy metal ions from aqueous solution.
