Abstract

The invention discloses a magnetic acrylic acid series strongly basic anion exchange microballoon resin and a preparation method thereof. The microballoon resin has the following structure: the resin skeleton is internally provided with magnetic particles, wherein A stands for a radical containing quaternary ammonium salt. The preparation method comprises the following steps: acrylic acid series substances serve as a monomer, the monomer is mixed with cross-linking agent and pore-forming agent to form oil phase; the oil phase is uniformly mixed with the magnetic particles and then suspension polymerization is carried out on the mixture; after going through amination and alkylation reaction, the polymerized magnetic polymer particles form the quaternary ammonium salt, namely the magnetic acrylic acid series strongly basic anion exchange microballoon resin. Exchange capacity of the resin is higher than any magnetic acrylic acid series strongly basic anion exchange microballoon resin ever found in existing literatures and reports and domestic market as well as foreign markets and can replace the traditional strongly basic anion exchange resin, thus being capable of being used for separating and removing soluble organisms in various water bodies, especially disinfection by-product precursor and multiple negative ions such as nitrate and phosphate.

Description

technical field

[0001] The invention discloses an acrylic strong base anion exchange microsphere resin and a preparation method thereof, more specifically an acrylic strong base anion exchange microsphere resin containing magnetic particles and a preparation method thereof. Background technique

[0002] At present, magnetic strong base anion exchange resins have been used to remove some impurities in water bodies. Due to the small particle size of this resin, usually 150-180 μm, it has a large specific surface area on the surface of the resin particles, so it shows good performance. dynamic performance. MIEX developed by Orica, Australia The resin is a macroporous acrylic structure with a strong base ion exchange group, so it is very sensitive to nitrate, sulfate, phosphate, arsenate and other anions in water, as well as dissolved organic pollutants, including some disinfection by-product precursors. Removal with good results.

[0003] The preparation of magnetic resin u...
