Embodiment 1

[0036] A method for preparing iron-loaded mesoporous carbon materials, using polyoxyethylene-polyphenylene ether-polyoxyethylene triblock copolymer PEO-PPO-PEO (F127) as a template without adding alkali, adding 1,3,5-trimethylbenzene, resorcinol, and hexamethylenetetramine synthesize ordered mesoporous polymer intermediates, and then add ferric citrate to prepare iron-loaded ordered mesoporous carbon materials, which are prepared according to the following steps:

[0037] a. Weigh 1.0g of F127 and dissolve it in 18g of water, add 0.2g of 1,3,5-trimethylbenzene (TMB), 0.55g

[0038] Resorcinol and 0.35 g of hexamethylenetetramine were stirred at room temperature for 2 h to obtain a clear solution.

Abstract

The invention discloses a preparation method for an iron-loading mesoporous carbon material, as well as a product and application thereof. In the condition of no alkali, a soft template method is adopted to synthesize the iron-loading ordered mesoporous carbon material in one step; polyoxyethylene-polyphenyl ether-polyoxyethylene triblock copolymer PEO-PPO-PEO(F127) is taken as a template; 1,3,5-trimethylbenzene, resorcinol and hexamine are added to synthesize ordered mesoporous polymer intermediate, and then, ferric citrate is added to prepare the iron-loading ordered mesoporous carbon material. The iron-loading mesoporous carbon material prepared with the preparation method has the advantages of high specific surface area, uniform aperture and good magnetism, and shows a good adsorptionfunction on the aspect of organic pollutant adsorption, and pollutants can be quickly separated.

Description

technical field [0001] The invention relates to the technical field of adsorption materials for organic pollutants in industrial wastewater, in particular to a preparation method of an iron-loaded mesoporous carbon material and its product and application. Background technique [0002] Water is the source of life, a necessary condition for the existence of life and economic development, and also an important part of human tissue. With the geometric growth of the population, the indiscriminate discharge of modern industrial waste water, urban garbage, rural pesticide spraying, etc., the shortage of fresh water resources, which are already very small, has been exacerbated and cannot be used by human beings. The main pollutants that cause water pollution can be roughly divided into three categories: organic matter (phenolic organic matter, pharmaceutical wastewater, chloroform, carbon tetrachloride, ammonia nitrogen, etc.); heavy metals (lead, mercury, manganese, cadmium, etc.)...
