Abstract

Provided is a novel activated carbon adsorbing material loaded with an imidazole ionic liquid. The novel activated carbon adsorbing material is prepared by the steps: weighing 1-methylimidazole and bromohexane into a container, carrying out a reaction in a constant-temperature oil bath pot, and thus obtaining a purified 1-hexyl-3-methylimidazolium bromide ionic liquid; adding the purified 1-hexyl-3-methylimidazolium bromide ionic liquid to powdered activated carbon in a flask, mixing evenly by magnetic stirring at constant temperature, drying to constant weight, and thus obtaining the novel activated carbon adsorbing material loaded with the imidazole ionic liquid. The novel activated carbon adsorbing material has the advantages that the novel composite material is good in stability, insoluble in water and most solvents, and high in heat resistance; a stable structure formed between particles is observed under a microscope, and the novel composite material has good adsorption effect oncopper ions and other metal ions, and can be used as a novel activated carbon adsorption material.

Description

technical field [0001] The invention relates to a novel activated carbon adsorption material loaded with imidazole ionic liquid. Background technique [0002] Activated carbon, also known as activated carbon black, is black powder or granular amorphous carbon; its pore structure is developed, and its specific surface area is 1500m 2 / g or more, it has adsorption capacity. Ordinary activated carbon has the characteristics of high ash content, small pore volume, wide micropore distribution, relatively small specific surface area, and poor adsorption selectivity. In addition, some limitations of its surface functional groups and electrochemical properties make it difficult to adsorb and remove pollutants. The effect is limited, and it is far from meeting the requirements of domestic and foreign markets. Therefore, in the process of water pollution treatment, it is necessary to modify the structure and properties of the activated carbon used to increase its adsorption capacity...
