Problems solved by technology

Because the concentration of acid in many boron-containing wastewater is very high, such as 1,4-dihydroxyanthraquinone wastewater contains 20% concentrated sulfuric acid, which is a strong acid system, so the above resins are not suitable for the recovery of boric acid in wastewater

Abstract

The invention relates to a special effect boron adsorption resin and a synthetic method and application thereof, belonging to the fields of high molecules and waste water treatment. The general structural formula of the resin is shown in the specifications, wherein n=1,000-2,000. The method comprises the following steps of: (1) preparing 2-amino-1,3-propylene glycol; (2) preparing chloromethylated styrene-divinylbenzene copolymerized spheres; and (3) preparing the special effect boron adsorption resin from the 2-amino-1,3-propylene glycol and the chloromethylated styrene-divinylbenzene copolymerized spheres. The special effect boron adsorption resin can be used for extracting and recovering boric acid from an acid aqueous solution. In the invention, the special effect boron adsorption resin which is suitable for a strongly acid environment is synthesized by taking 1,3-propylene glycol as a functional group.

Description

technical field The invention relates to the synthesis and application of a special-effect boron adsorption resin, which belongs to the field of polymer and waste water treatment. Background of the invention Boron is widely used in industry, and the separation and removal of boric acid in water is of great significance. Common anion exchange resins can adsorb boric acid from aqueous solutions. However, the selectivity to boric acid is not very good, and the adsorption capacity of boric acid is poor when the electrolyte concentration in water is high, so the boron selective resin based on polyhydroxylation has been developed, and the earliest boron selective resin appeared in 1957. Lyman and Preuss prepared a resin by reacting oxymethylated polystyrene with N-methylglucamine. Its reaction formula is as follows: This resin was originally synthesized as a gel type, and then a macroporous resin was synthesized. D564 is the earliest domestically produced resin with specia...
