Abstract

The invention provides a preparation method of a magnetic organic conjugated polymer microsphere. The preparation method comprises the steps of polymerizing acetylenyl benzene and halogeno benzene on a Fe3O4 surface to obtain a polymer; forming a hollow tubular polymer by using the polymer; and covering the hollow tubular polymer on the Fe3O4 surface to obtain a hydrophobic micro-nano structure to form a magnetic, oleophilic and hydrophobic microsphere. The polymer material prepared by using the method can selectively adsorb / separate oil or a nonpolar organic solvent in a water body. The polymer can be separated from a solution under the action of a magnetic field after being saturated through adsorbing organic matters in the mixed solution. Obviously, the recovering method is simple, high in operability and regenerating speed and capable of reducing the adsorption and separation costs so as to have a potential application value in the fields of crude oil leakage treatment, industrial organic wastewater treatment, liquid / liquid separation, water treatment, catalysis and the like.

Description

Technical field [0001] The invention belongs to the field of polymer material synthesis and application, and specifically relates to a method for preparing magnetic organic conjugated polymer microspheres, and the application of this material in removing organic compounds in water. Background technique [0002] Water resources are an important material basis for sustainable economic and social development. However, water pollution caused by the discharge of industrial organic waste liquids and marine environmental pollution caused by crude oil leakage have caused serious ecological disasters to freshwater resources and the marine environment. For example, high-concentration organic wastewater is produced in the petrochemical production process. Due to the complex composition and high content of organic compounds, the water body is eutrophication and the loss of animal and plant species. The organic matter forms a film and gathers on the surface of the water body, which affects th...
