Preparation method of silanized active carbon and preparation method of immobilized enzyme

The invention relates to the field of biochemical engineering, and in particular relates to a preparation method of silanized active carbon and a preparation of immobilized enzyme. According to the invention, the preparation method of silanized active carbon comprises the steps of reserving active carbon, and oxidizing the active carbon to obtain oxidized active carbon; and carrying out silanization on the oxidized active carbon and a silane coupling agent with the presence of an organic solvent and water, to obtain the silanized active carbon, wherein dosage ratio of the oxidized active carbon to the water is 1: (0.05-0.2) according to g/ml. The preparation method of the immobilized enzyme disclosed by the invention can greatly improve immobilizing amount of bio-enzyme and improve enzyme activity.
