Abstract

The invention discloses a macroporous cross-linked adsorption resin containing tertiary amine hydrochloride functional groups and a preparation method thereof. The present invention uses a trifunctional group crosslinking agent (trimethylolpropane trimethacrylate) and a functional monomer (dimethylaminoethyl methacrylate) as raw materials to prepare trimethylolpropane trimethacrylate through free radical suspension polymerization. Methacrylate tertiary amine resin, after soaking and modifying its tertiary amine group ‑N(CH3)2 with hydrochloric acid, a macroporous cross-linked resin containing tertiary amine hydrochloride functional groups can be obtained, which can be used for toxic and Adsorption removal of oxoacid anions (perchlorate, bromate, arsenite and arsenate). The novel adsorption resin developed by the present invention has the characteristics of environmental protection, high efficiency and wide adaptability, etc., and is used to solve the safety problem of drinking water, so as to realize the production of safe, environment-friendly and clean drinking water.

Description

technical field

[0001] The invention belongs to the technical field of purification and pollutant treatment of drinking water sources, and in particular relates to a macroporous cross-linked adsorption resin containing tertiary amine hydrochloride functional groups and a preparation method thereof. Background technique

[0002] At present, the safety of drinking water, especially the impact of micro-pollutants on human health has become one of the research hotspots in the field of environment. Unlike organic pollutants, toxic oxyacid anions are highly mobile and cannot be easily removed. Therefore, the removal of toxic oxoacid anions such as perchlorate, bromate, arsenite, and arsenate from water is essential for the protection of humans and the environment.

[0003] Among them, perchlorate (Perchlorate, ClO 4 - ) is a new type of inorganic pollutant. Due to its high stability, high water solubility and strong oxidizing properties, it is often used as a safe oxidizing ag...
