Heavy metal removal by biosorption using Phanerochaete chrysosporium

摘要: Biosorption using microbial cells as adsorbents is being seen a cost-effective method for the removal of heavy metals from wastewaters. studies with Phanerochaete chrysosporium were performed copper (II), lead and cadmium (II) to evaluate effectiveness optimize operational parameters response surface methodology. The chosen initial metal ion concentration, pH, biosorbent dosage. Using this method, could be correlated parameters, their values optimized. results showed fairly high adsorptive capacities all within settings parameters. efficiencies followed order Pb>Cu>Cd. As general trend, efficiency decreased concentration increased, fitted Langmuir Freundlich isotherms well.
