Abstract

The invention relates to weak-polarity macroporous resinfor removing nitrobenzene in wastewater and a preparation method of the weak-polarity macroporous resin, and belongs to the technical field of macroporous adsorption resin. According to the physicochemical properties of an adsorption object and based on the weak polarity of nitro on a benzene ring and a macromolecule design principle, a small amount of third polymerization component acrylonitrile is added into a polymerization system, and a crosslinking agent dimethacrylate-1,6-glycol ester with certain polarity and a hydrophobic crosslinking agent divinyl benzene are blended into a mixed crosslinking system; weak-polarity macroporous adsorption resin with certain polarity and relatively good adsorption property on nitrobenzene is prepared by a suspension polymerization technology.

Description

technical field [0001] The invention relates to a weakly polar macroporous resin and a preparation method thereof, more specifically, the present invention relates to a weakly polar macroporous resin for removing nitrobenzene in waste water and a preparation method thereof, belonging to macroporous adsorbent resins technology field. Background technique [0002] Macroporous adsorption resin has a huge specific surface area (generally 200-800m 2 / g resin), is a kind of polymer material with adsorption function. It is widely used in the field of environmental protection because it can effectively adsorb various medium molecular weight (about 100-100D) organic substances dissolved in water in aqueous solution. With the development of human society, water pollution has become a serious problem before us. Among them, nitrobenzene-containing wastewater is large in volume, highly toxic, and seriously pollutes the environment. Therefore, the research and development of this kind...
