Embodiment

[0033] The microbial fuel cell anode immune modification of the present embodiment is as follows: figure 1 As shown, the amino group is chemically modified on the surface of the anode of the microbial fuel cell or the aldehyde group is modified, and then the amino group is modified, and then the antibody adsorbed with colloidal gold is bound to the surface of the anode. Experiments show that the above design parameters are suitable for immobilizing various electrogenic microorganisms on the anode membrane of microbial fuel cells.

[0034] Specific steps are as follows:

[0035] 1) Preparation of colloidal gold particles: a chemical reduction method was used to prepare colloidal gold particles of 1-1000 nm.

[0036]Colloidal gold is prepared by a reduction method, mainly using a reducing agent to reduce chloroauric acid (HAuCl4). The commonly used reducing agents are sodium citrate, tannic acid, ascorbic acid, white phosphorus, sodium borohydride and so on. When preparing, f...

Abstract

The present invention discloses an immune modification treatment method for an anode of a microbial fuel cell. The method is characterized in that: the anode of the microbial fuel cell is treated through the following ways: firstly modifying chemical molecule groups on the anode surface of the microbial fuel cell; adopting the chemical molecule groups to fix the colloidal gold particle-modified anti-electricigen antibody to form the anode of the immune modification treated microbial fuel cell. According to the method, the contact chance of the microbial and the anode surface is improved, and the electrical conduction efficiency between the microbial and the anode is improved.

Description

technical field [0001] The invention belongs to the technical field of research and development of microbial fuel cells, and in particular relates to a microbial fuel cell anode and an immune modification treatment method thereof. Background technique [0002] Microbial Fuel Cells (MFC) is a device that uses microorganisms to directly convert chemical energy in organic matter into electrical energy. As a power source technology for direct power generation, microbial fuel cells provide new principles and new methods for applications in the fields of biomass power generation, sewage treatment, and aerospace. Because microbial metabolism consumes organic matter while generating electricity, it has a purifying effect on environmental pollution, and it is currently attracting attention. [0003] The basic working principle of microbial fuel cell is: in the anaerobic environment of the anode chamber, the organic matter is decomposed under the action of microorganisms and releases...
