Problems solved by technology

Although there are many studies on the adsorption of pollutants in water by modified attapulgite at home and abroad, the quaternary ammonium salts (such as hexadecyl trimethyl chloride (bromine) mainly with long-chain alkyl groups as lipophilic groups ammonium chloride and cetylpyridinium bromide, etc.) modified attapulgite, but the above-mentioned surfactants have certain potential harm to the environment and ecology
At present, there is no report on how to use the adsorption of N,N-dimethyl dehydroabietyl amine oxide modified attapulgite to remove humic acid, anionic dyes and anionic inorganic ions in water.

Abstract

The invention discloses a preparing method and application of tertiary amine oxide modified attapulgite containing a rosinyl ternary phenanthrene ring structure and belongs to the technical fields of water source purification and pollutant treatment. The preparing method comprises the steps of acidizing and firing attapulgite with hydrochloric acid solution firstly, and then modifying attapulgite with tertiary amine oxide containing the rosinyl ternary phenanthrene ring structure to prepare the tertiary amine oxide modified attapulgite containing the rosinyl ternary phenanthrene ring structure. The adsorbent can be applied to removal of environment pollutants including humic acid, fluorinion and Congo red in drinking water. The preparing process is simple, utilization rate is high, cost is low, application range is wide, operation is easy, both a modifier and a matrix are environment-friendly materials, and popularization is easy.

Description

technical field [0001] The invention belongs to the technical field of water source purification and pollutant treatment, and relates to an adsorbent, in particular to the modification preparation and application of a modified attapulgite adsorbent. Background technique [0002] In recent years, with the rapid development of my country's social economy, the discharge of water pollutants has increased year by year, and the problem of micro-pollution in the water environment has become increasingly prominent. The pollution of surface water bodies not only poses a threat to aquatic organisms, but also destroys the ecological environment, and ultimately endangers human health. Many pollutants such as humic acid, fluoride ions, and dyes from industrial wastewater exist in the surface water of our country, such as rivers, lakes, and reservoirs. Therefore, it is an urgent task to develop effective treatment methods to reduce natural organic matter represented by humic acid, inorga...
