Embodiment 1

[0030] A method for preparing polymeric materials with monosaccharides and methyl methacrylate, comprising the following steps: dissolving 1 to 10 parts of mannose in 5 to 15 parts of distilled water, and then adding 0.1 to 3 parts of potassium persulfate (or Sodium sulfate or ammonium persulfate) as the initiator, stir well to dissolve the two (uniform dispersion), add 1 to 50 parts by mass of methyl methacrylate monomer to the above mixed solution, and stir at 20 to 100 ° C After reacting for 1-10 hours, cool naturally to room temperature, powder (chop) it with appropriate methods, wash with water, purify, and dry to constant weight at 30-80°C to obtain the final product.

Embodiment 2

[0032] A method for preparing polymeric materials with monosaccharide and methyl acrylate, comprising the following steps: dissolving 1-10 parts of glucose in 5-15 parts of distilled water, and then adding 0.1-3 parts of potassium persulfate (or sodium persulfate or persulfate ammonium sulfate) as the initiator, fully stir to dissolve the two (uniformly dispersed), add 1 to 60 parts by mass of methyl acrylate monomer to the above mixed solution, and stir and react at 20 to 100°C for 1 to 12 hours Naturally cool to room temperature, use appropriate method to grind (cut) the powder, wash with water, purify, and then dry to constant weight at 20-100°C to obtain the final product.

Embodiment 3

[0034] A method for preparing polymeric materials with monosaccharide and methyl methacrylate, comprising the following steps:

[0035] a. Ingredients mixing: Dissolve 5 parts by mass of monosaccharide in 10 parts by mass of distilled water, then add 1.5 parts by mass of initiator potassium persulfate, (full) stir and mix (so that the solid dissolves or disperses evenly), and then adds 25 parts by mass The methyl methacrylate, obtains the reaction mixture;

[0036]b. Polymerization reaction: After the reaction mixture was stirred and reacted for 6 hours at a temperature of 60°C, it was naturally cooled to room temperature to obtain the reacted material;

[0037] c. Post-treatment: Grinding (or chopping) the reacted material, washing it with water for 2 to 5 times (to purify it), and then drying it at a temperature of 20 to 100°C (to a constant weight) to obtain a polymer material product.

Abstract

The invention discloses a preparation method of a polymeric material by utilizing monosaccharide and methyl methacrylate (or methyl acrylate). The preparation method is characterized by comprising the following steps of: dissolving 1-10 parts by weight of monosaccharide in 5-15 parts by weight of distilled water, adding 0.1-3 parts by weight of initiator potassium peroxydisulfate, stirring for mixing, and adding 1-50 parts by weight of methyl methacrylate (or methyl acrylate), to obtain a reacting mixture; reacting the reacting mixture for 1-10 hours under the temperature condition of 20-100 DEG C while stirring, and naturally cooling into room temperature, to obtain a material after reaction; and smashing the material after reaction, washing with water, and drying, so as to obtain a polymeric material product, wherein the monosaccharide can be one or a mixture of at least two of mannose, glucose, fructose and galactose. After the preparation method is adopted, the prepared polymeric material comprises a plurality of lone pair electrons-containing adsorption sites, has certain complexing power with metal ions, and can be directly used for treating heavy metal ion waste water.

Description

technical field [0001] The invention belongs to the preparation of monosaccharide-based derivatives, and relates to a method for preparing polymeric materials by using monosaccharide and methyl methacrylate or methyl acrylate. It is suitable for the preparation of new bio-based copolymer materials of monosaccharide-based methyl methacrylate or methyl acrylate. The polymeric material prepared by adopting the present invention is particularly suitable for treating heavy metal ions (Pb 2+ 、Cd 2+ , Hg 2+ 、Cr 3+ 、Cr 6+ 、Ag + 、Cu 2+ , Zn 2+ etc.) Adsorption treatment of wastewater. Background technique [0002] With the rapid development of modern industry, the harm of heavy metal sewage to the environment and human health is becoming more and more serious. Heavy metal wastewater mainly comes from mining, mineral processing, smelting, electroplating, chemical industry, machinery and other industries. After the heavy metal wastewater produced by these industries is discha...
