The amount of Zn(II) ion sorption by the beads was as follows; orange peel cellulose with Phanerochaete chrysosporium immobilized Ca-alginate beads (OPCFCA) (168.61mg/g)orange peel cellulose immobilized Ca-alginate beads (OPCCA) (147.06mg/g) P. chrysosporium (F) (125.0mg/g)orange peel cellulose (OPC) (108.70mg/g)plain Ca-alginate bead (PCA) (98.26mg/g). The Zn.sup.2+ concentration was 100 to 1000mg/L. The widely used Langmuir and Freundlich isotherm models were utilized to describe the biosorption equilibrium process. The isotherm parameters were estimated using linear and non-linear regression analysis. The Box-Behnken model was found to be in close agreement with the experimental values, as indicated by the correlation coefficient value of 0.9999.
