Conclusion

In this work the efficiency of the immobilization method based on avidin-biotin technology linked to an intermediate electropolymerized polymer layer onto carbon fibers for the building of a catalytic filtration membrane has been demonstrated. The enzyme activity of this new type of membrane along with the kinetic parameters have been determined in the case of the dismutation of H2O2. These rate parameters are not too much affected by the immobilization process, as the loss of reactivity as compared to free enzymes was shown to be moderate. Moreover, the long-term stability of the catalytic activity of this type of reactive membrane makes it a promising candidate for practical application in membrane technology for liquid transformations.
