Problems solved by technology

However, the preparation method of the composite material reported in the literature is relatively complicated, and 1,3,6,8-pyrene tetrasulfonic acid tetrasodium salt needs to be added as a dispersant and adhesion agent, and the composite material is only used for the removal of methylene blue
The literature "Inyang, M., Gao, B., Zimmerman, A., Zhang, M., Chen, H. 2014. Synthesis, characterization, and dyeesorptionability of carbonnanotube–biocharnanocomposites. Chemical Engineering Journal, 236,39-46" reported the use of dipping method Prepare carbon nanotube/biochar composite mate

Embodiment

[0017] In order to investigate the adsorption effect of G / BC on low-concentration phenanthrene and mercury(II) in wastewater, the experimental groups were set up as follows: (1) biochar (BC); (2) G / BC-0.1%; (3) G / BC BC - 0.5%; (4) G / BC - 1%; (5) Control group, only wastewater (CK).

[0018] Add 120mL of a phenanthrene solution with a concentration of 1000ppb to a 120mL brown glass bottle with a polytetrafluoroethylene-lined lid, and add 28mL of a mercury (II) solution with a concentration of 400ppb to a 30mL polytetrafluoroethylene bottle, and follow the above settings to arrange experiments. The reaction experiment of phenanthrene was equilibrated for 3 days in a reciprocating shaker at 150rpm, 25oC, protected from light, and the reaction experiment of mercury(II) was equilibrated for 5 days on a rotary shaker at 40rpm, 25oC. All experiments Both the control group and the control group were set up in three parallel groups. After the experiment was completed, the supernatant...

Abstract

The invention provides a biological carbon/graphene composite used for adsorbing organic/inorganic pollutant in a water body and a preparation method, and discloses the biological carbon/graphene composite easy and convenient to use and the preparation method. The biological carbon/graphene composite is used for adsorbing organic/inorganic pollutant in the water body. According to the technical scheme, biomass raw materials are directly processed through graphene suspension, anaerobic pyrolysis is conducted for 1 h under the condition of 600 DEG C in a tubular furnace after the mixture of the graphene suspension and the biomass raw materials is dried so that graphene can wrap the surfaces of biological carbon through pi-pi bonds, the biological carbon/graphene composite is endowed with a larger specific area and more functional groups through the outer layers of graphene, and therefore the removal effect of the biological carbon/graphene composite for phenanthrene and mercury (II) in water is remarkably improved. The biological carbon/graphene composite and the preparation method have the advantages that the process is simple, the effect is table, the application range is wide, the composite is friendly to the environment, and no secondary pollution is caused; the biological carbon/graphene composite and the preparation method have wide application prospects on the aspect of repairing organic/inorganic pollution in the water body.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and relates to a biochar / graphene composite material for absorbing organic / inorganic pollutants in water bodies and a preparation method thereof. Background technique [0002] The removal of low-concentration polycyclic aromatic hydrocarbons and mercury(II) in wastewater has always been one of the hotspots and difficulties in environmental science research. Adsorption is a common wastewater treatment method, which has the advantages of good effect, fast treatment, and simple operation. The performance of the adsorbent plays a decisive role in the adsorption effect of pollutants. Therefore, the research and development of environmentally friendly, low-cost and effective adsorbents It is the focus of improving the adsorption effect. [0003] Biochar has high carbon content, large porosity and specific surface area. It is a natural adsorption material with high adsorption performance and lo...
