| Abstract: | The immobilization methods were studied in this paper.The immobilization methods were primarily screened by evaluating the mechanical intension and permeability of immobilized cell granules.The influence on buffer of immobilized cells was studied later and the optimum immobilized method was selected.The batch experiment results indicated that the immobilized cell granules obtained by active carbon-CA complex treated and intensified by 0.6% polyethylene imine and 1% Glutaraldehyde had the best mechanical intension,permeability and endurance on phosphate buffer solution. |
