The invention discloses a preparation method of a polymethyl methacrylate macroporous microsphere adsorbent. The preparation method comprises the following steps: firstly, adding a styrene monomer which is dissolved with azodiisobutyronitrile into an alcohol-aqueous solution of polyvinylpyrrolidone to synthesize hydrophobic polystyrene microspheres; then, adding the hydrophobic polystyrene microspheres into concentrated sulfuric acid for cleaning after sulfonating in an oil bath, and drying to obtain sulfonated polystyrene microspheres which are amphipathic substances with hydrophilcity and lipophilicity; and finally, dispersing the sulfonated polystyrene microspheres into an aqueous phase as a stabilizer, adding single monomer methyl methacrylate into the aqueous phase as an oil phase for mixing, and magnetically stirring to prepare stable oil-in-water Pickering emulsion, and preparing a macroporous polymer with a great specific surface area by utilizing thermal-initiation polymerization. |
