In this study, application of immobilized Horsradish Peroxidase (HRP) on calcium alginate to removal of acid blue 25 and acid orange 7 from waste water was studied. Experimental study of optimum condition for immobilization of HRP on calcium alginate and then, removal efficiency of acid blue 25 and acid orange 7 by immobilized HRP and also toxicity of by-products with bioassay were studied. Results show that immobilized HRP at optimum condition have 80% color removal efficiency from polluted wastewater. Results show alginate beads after 10 replicate usages without change in activity were reusable. Bioassay of by-products by D.Magna show that this method of treatment lead to decrease significantly in toxicity of dye from treated wastewater.
