Abstract

The invention discloses a preparation method of a strong-alkaline compound acrylic anion exchange resin. Based on the traditional production process, through reasonable matching of a suspending protective agent, a dispersing agent, a pore-foaming agent and a complexing agent and optimizing processing parameters, the anion exchange resin prepared by the method has the effects of uniform pore distribution and improved exchange capacity. According to the preparation method, the specific surface area of the prepared ion exchange resin is more than 60m<2> / g, the proportion of mesopores larger than 2nm is greater than 60%, and the complete exchange capacity reaches 4.9 mmol / g.

Description

technical field [0001] The invention belongs to a preparation method of an ion exchange resin, in particular to a preparation method of a strongly basic composite acrylic anion exchange resin. Background technique [0002] Anion and cation exchange resins are widely used in water treatment, material purification, concentration, separation, transformation of material ion composition, material decolorization, and catalysts. Although the exchange capacity of the current anion and cation exchange resins has been effectively improved, the pore size distribution is uneven and the exchange rate is low. Insufficient switching capacity and other issues cannot meet customer requirements. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method of a strongly basic composite acrylic anion exchange resin. The present invention improves the dispersibility and suspension through the improvement of the water phase, thereby increasing the ...
