Abstract

The invention discloses an amphiphilic polymeric micro-spherical material uniform in grain size, a preparation method and an application and belongs to the field of high molecular materials and solvesthe problems that an existing preparation method is hard to regulate grain size, low in polymer yield, poor in application effect and the like. The preparation method comprises the following steps: by taking N-vinyl pyrrolidone and divinylbenzene as a monomer, dispersing an emulsion uniformly in a water phase by a certain way; strengthening affiliation of the hydrophobic monomer divinylbenzene and the hydrophilic monomer N-vinyl pyrrolidone to increase the yield by means of proper water phase composition and proportion; and carrying out polymerization in conditions of a strict temperature androtating speed and the like to finally obtain the amphiphilic polymeric resin material uniform in grain size. Through serial representation and application evaluation, the material has very excellentamphiphilic performance, has a wide broad enriching and separating property to organic matters in a water body, and can be separately applied to the fields of analysis, detection, water treatment projects, household water purification and the like according to the grain sizes.

Description

technical field

[0001] The invention belongs to the field of preparation methods and applications of polymer materials, and in particular relates to an amphiphilic polymer microsphere material with uniform particle size, a preparation method and applications thereof. Background technique

[0002] In recent years, environmental pollution has received more and more attention. Emerging organic pollutants have become a research hotspot in recent years. Although the environmental concentration is low, they have become a problem to be solved urgently because of their wide distribution and high toxicity. Adsorption is currently the main method for removing micro-polluting organic matter, and it is also the method recommended by the US EPA for many types of micro-polluting organic matter. However, there are many kinds of these pollutants. Most of the existing adsorbents such as activated carbon have good effect on hydrophobic organic substances, but it is difficult to efficiently a...
