Description

technical field [0001] The invention belongs to the technical field of material preparation and water treatment, and in particular relates to a PDDA protonated graphite phase carbon nitride and its preparation method and application. Background technique [0002] Dye is a typical representative organic pollutant, mainly from dye synthesis, printing and paper industry, has been detected in many rivers because of its non-biodegradable, carcinogenic, bioaccumulative, high The depth of color has attracted widespread attention. The treatment methods of dye wastewater include biological treatment, adsorption, chemical oxidation, membrane separation, electrodialysis, and ion exchange. Among these methods, adsorption technology is low in cost, simple in operation, and effective in environmental protection. Ideal for dyes. Among them, activated carbon has become a popular choice for adsorbing dyes in wastewater, but its high cost poses economic problems. [0003] CN110975917A disc...
