▎ 摘  要

NOVELTY - Compound loaded on porous carbon-based material is prepared by dissolving the metal mixed salt and the organic ligand in the solvent of the corresponding solubility respectively, dissolving and dispersing uniformly by ultrasonication, fully mixing the above two solutions under stirring conditions, and then transferring to the condensation reflux reactor. The hydrothermal reaction is carried out at 80-180°C for 2-4 hours to obtain the mixed ligand compound loaded with mixed metal salt. A specific amount of the element-doped porous carbon support material is put into the reaction solution, and the reaction is continued for 4-8 hours. The resultant solution is cooled, filtered under suction, repeatedly washed with the corresponding solvent, then dried until the water content less than 8% and transferred to a furnace protected by an inert gas and calcined at 800-950°C for 1-4 hours to obtain final compound. USE - Compound loaded on porous carbon-based material for use in water treatment (claimed). ADVANTAGE - The compound loaded on porous carbon-based material is prepared by using cheap and easily-obtained raw materials, in a simple and cost effective manner. The compound loaded on porous carbon-based material has the capability of degrading refractory organic matters through a free radical path and a non-free radical path of active oxygen species under the operating condition of normal temperature and normal pressure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for applying a compound loaded on a porous carbon-based material to water treatment. The coordination compound catalyst particles are packed in a reactor with a micro-ceramic aeration disc at the bottom in the form of a fixed bed, and the bubble size is 50-400 µm. The gas source is air, 90%±3% concentration of enriched oxygen and pure oxygen prepared by pressure swing adsorption oxygen generator. The hydraulic retention time of the reaction is adjusted by adjusting the flow rate of the water pump at the inlet end. The organic pollutants are degraded through two pathways ie., free radicals and non-radicals. The common oxidizing species in the free radical pathway are hydroxyl radicals and sulfate radicals. The common oxidizing species in the non-radical pathway are superoxide radical and singlet oxygen, and degradation pathway is qualitatively quantified indirectly by the degree to which the efficiency of the oxidative degradation reaction is attenuated by the use of a specific annihilating agent.
