Preparation method of ion exchange gel electrode for capacitive deionization technology

The invention provides a preparation method of an ion exchange gel electrode for a capacitive deionization technology, and relates to the technical field of capacitive deionization. Comprising the steps of preparing a polymer solution, adjusting an acidic polymer, preparing ion exchange gel electrode slurry and preparing an ion exchange gel electrode. The polyvinyl alcohol is used as a hydrophilic binder, the affinity between the electrode and water is strong, charged ions easily penetrate through an interface to enter electrode material pore channels, and the adsorption capacity is improved. The polyvinyl alcohol polyquaternium-10 is easy to contain a large amount of-OH, and hydrogen bonds can be formed between the polyvinyl alcohol polyquaternium-10 and the-OH, so that good compatibility is realized, and the components in the electrode are uniformly distributed and are uniform in composition. Glutaraldehyde is introduced to be crosslinked with a hydrophilic binder polyvinyl alcohol, and polyquaternium-10 is
