Embodiment Construction

[0035] The present invention provides a polyphenol-modified gamma-type alumina-based porous carbon composite material for efficiently treating medical wastewater containing rifapentine antibiotics as gamma-Al 2 o 3 / C BT-900 The composite material is composed of nanoparticles with a length of 100-200 nm and a relatively uniform size. And use it as the removal material of rifapentine molecules.

[0036] The present invention will be further described below by means of drawings and embodiments. It must be pointed out that the following examples are only used to further illustrate the present invention, and should not be interpreted as limiting the protection scope of the present invention. Those skilled in the art will make some non-essential improvements and adjustments to the present invention according to the above-mentioned content of the invention. Implementation still belongs to the protection scope of the present invention.

[0037] This example demonstrates a synthes...

Abstract

The invention belongs to the field of rifamycin adsorption materials, and in particular relates to a polyphenol-modified gamma-type alumina-based porous carbon composite material, a preparation method and an application. The polyphenol-modified gamma-type alumina-based porous carbon composite material is gamma-(Al 2 o 3 ) 1.333 / C BT‑900 Composite materials are composed of nanoparticles with a length of 100-200 nm and uniform size. Polyphenol-modified gamma-type alumina-based porous carbon composite material gamma-Al provided by the invention 2 o 3 / C BT‑900 As a new removal material for rifapentine molecules, it can exert the synergistic effect of nanoporous carbon and metal oxides, further increase the specific surface area of ​​the material, and increase the contact area and adsorption sites with rifapentine. Using it as a novel adsorbent for rifapentine shows good adsorption performance.

Description

technical field [0001] The invention belongs to the field of rifamycin adsorption materials, and in particular relates to a polyphenol-modified gamma-type alumina-based porous carbon composite material, a preparation method and an application. Background technique [0002] Rifamycin antibiotics are mainly used to treat tuberculosis, which is known as the second largest infectious disease in the world. As rifapentine, which has similar antibacterial spectrum properties to rifampicin, its anti-tuberculosis ability is far better than rifampicin , but it also has side effects such as liver toxicity and teratogenicity. Even if it is in a low concentration state in water, it will still cause adverse effects on the natural environment and human health. In recent years, methods to deal with antibiotics have emerged in an endless stream, such as ion exchange, solvent extraction, and Fenton oxidation, etc., which can deal with organic pollutants to a certain extent, but they also face...
