Problems solved by technology

[0004] The development of adsorbent materials usually starts with the preparation of new adsorbent materials and the activation and modification of adsorbent materials. However, it focuses on the study of the adsorption properties of the adsorbate while ignoring the antibacterial properties, which leads to the single function of the adsorbent, The scope of application is limited, and the adsorbent itself is easy to breed bacteria; for inorganic antibacterial metals, not only does it not have the adsorption capacity, but its function is single, and its antibacterial effect is also easily affected by light and heat, and it is easy to be damaged by long-term use. reduce the antibacterial effect

Embodiment 1

[0033] Weigh 2.7g 3-aminophenol and dissolve it in the mixed solution of 252ml deionized water / absolute ethanol / mass concentration 25%-28% ammonia water (deionized water: absolute ethanol: the volume of mass concentration 25%-28% ammonia water The ratio is 2000:800:9), stirred at 30°C for 10 minutes, then added 0.5783g of copper acetate under stirring, and continued to stir for 30 minutes to obtain a pre-reaction solution. Add 3.645ml of formaldehyde solution with a volume fraction of 37% to the pre-reaction solution, and stir the reaction solution in a water bath at 30°C for 4 hours. Then pour the reaction solution into a 100ml polytetrafluoroethylene liner (filling rate is 70%-80%), put the polytetrafluoroethylene liner into a hydrothermal reaction kettle, seal it and place it in an oven at Hydrothermal reaction was carried out at 110°C for 24 hours, and after the reaction was completed, it was quenched to room temperature with tap water. The hydrothermal reaction product w...

Embodiment 2

[0035] The carbon material adsorbent was prepared with reference to the method of Example 1, except that 2.7 g of 3-aminophenol was replaced by 2.7 g of 4-aminophenol to obtain a copper-loaded modified bismuth with a copper loading of 10 wt.%. Functional carbon material adsorbent Cu-CAF.

Embodiment 3

[0037] The carbon material adsorbent was prepared with reference to the method of Example 1, the difference was that 2.7 g of 3-aminophenol was replaced by 2.7 g of resorcinol to obtain a copper-loaded modified bismuth with a copper loading of 10 wt.%. Functional carbon material adsorbent Cu-CRF.

Abstract

The invention particularly relates to a difunctional carbon material with adsorption and antibacterial properties and a preparation method thereof. The preparation method comprises the following steps: firstly, simultaneously dissolving phenols and soluble metal salt in an alkaline polar mixed solution to obtain a pre-reaction solution, then adding an aldehyde compound into the pre-reaction solution, stirring for a period of time, and carrying out a hydrothermal reaction to prepare the composite material by a one-step method; and carrying out high-temperature calcination in inert gas to prepare the metal modified bifunctional carbon material adsorbent. The product obtained by the invention has high toluene adsorption capacity which is increased by about 50% compared with that before modification; and in the antibacterial aspect, escherichia coli can be completely killed.

Description

technical field [0001] The invention belongs to the technical field of air purification and medical protection, and in particular relates to a dual-functional carbon material with both adsorption and antibacterial properties and a preparation method thereof. Background technique [0002] Most benzene series are toxic, and excessive exposure to benzene series will cause harm to human health, mainly in the following aspects: nervous system disorders, acute poisoning, abnormal liver function, carcinogenic, etc.; and benzene series are discharged into the atmosphere It will also cause environmental problems such as photochemical pollution. Air microorganisms such as bacteria and fungi are one of the important parameters of indoor air quality. Indoor air microbial pollution can cause eye irritation, asthma, allergic dermatitis, hypersensitivity pneumonitis and infectious diseases, and even death in severe cases. It can also be called "Bad Building Syndrome" (Kemp PC , Neumeister...
