Abstract

The invention provides a preparation method for an anode device of a microbial fuel cell. The preparation method comprises the following steps of dissolving methacrylic acid in dichloromethane; adding dicyclohexylcarbodiimide and alkylamine osmium bipyridine chlorate for reaction; drying an organic phase to obtain a monomer Y after washing; dissolving 2-methacryloyloxyethyl phosphorylcholine, 2-butyl methacrylate, 4-vinylbenzene boronic acid and the monomer Y in absolute ethyl alcohol; adding azodiisobutyronitrile for reaction; depositing a product in a chloroform / ethyl ether mixed solvent, dissolving the product in deionized water, and carrying out reduced pressure distillation to obtain a copolymer PMBVY; mixing the copolymer PMBVY and a culture solution loaded with Shewanella to obtain a constituent I; mixing polyvinyl alcohol and a sterile culture solution to obtain a constituent II; placing an electrode in a die; adding the constituents I and II in same volume; uniformly mixing the constituents I and II until a sol is cured; and combing the electrode, an electrode plate, a substrate and a filter net to obtain the anode device. By the method, materials are recycled, and the anode device is convenient to maintain.

Description

technical field [0001] The invention belongs to the field of biological fuel cells, and in particular relates to a method for preparing an anode device of a microbial fuel cell. Background technique [0002] Microbial fuel cell (MFC) is a kind of device that uses microorganisms to oxidize organic substrates and provide electrons for electrodes. This type of device can provide electricity while purifying organic pollutants that may have harmful effects on the environment. It has huge economic and social benefits. benefit. [0003] In an MFC, microorganisms oxidize an organic substrate at the anode to produce electrons and protons, the electrons are transferred to the anode and flow to the cathode through an electrical circuit connected to the cathode chamber, which contains an oxidizing agent (such as oxygen), and the electrons and protons reduce the oxidizing agent, This creates a potential difference between the anode and cathode and drives current through the external cir...
