NOVELTY - Preparing aluminum-metal organic framework (MOF)s doped carbon loaded polyurethane foam porous composite material, comprises (a) dissolving aluminum salt and organic acid in deionized water, stirring at room temperature until completely dissolved, transferring to a reaction kettle, performing hydrothermal synthesis reaction at 100 degrees C for 24 hours, and obtaining aluminum-metal organic frameworks (Al-MOFs) nanoparticle by centrifugal method, and (b) adding Al-MOFs nanoparticle, a carbon material and a polyurethane foam in the reaction kettle, taking water as solvent, reacting at 100 degrees C for 24 hours, loading the Al-MOFs and carbon material in the polyurethane foam material, and obtaining Al-MOFs and carbon-polyurethane foam porous polymer composite material. USE - The prepared composite material is useful for processing fluorine containing waste water. ADVANTAGE - The composite material has good fluorine ion removing effect even at low concentration and optimizes the water quality.
