title: Comparative study of the kinetics and equilibrium of phenol biosorption on immobilized white-rot fungus Phanerochaete chrysosporium from aqueous solution.
abstract: In this study the kinetics and equilibrium of phenol biosorption were studied from aqueous solution using batch technique at an initial pH of 5.5. The biosorption was studied on Ca-alginate beads, on non-living mycelial pellets of Phanerochaete chrysosporium immobilized on Ca-alginate, and on free fungal biomass. Ph. chrysosporium was grown in a liquid medium containing mineral and vitamin materials with complex composition. The biosorption process followed pseudo second-order kinetics on all bioadsorbents. The bioadsorption-equilibrium on blank Ca-alginate, free and immobilized fungal biomass can be described by Langmuir, anti-Langmuir and Freundlich isotherm models using nonlinear least-squares estimation.
