Abstract

The invention discloses a method for treating organic pollutants by utilizing a chitosan-modified activated coke in-situ supported nanogold catalyst. The method adopts the chitosan-modified activatedcoke in-situ supported nanogold catalyst to catalytically treat organic pollutants, wherein the chitosan-modified activated coke in-situ supported nanogold catalyst comprises activated coke, chitosanand nanogold particles, the surface of the activated coke is modified by the chitosan, so that a chitosan / activated coke compound is formed, and the nanogold particles are loaded on the chitosan / activated coke compound. In the invention, by adopting the chitosan-modified activated coke in-situ supported nanogold catalyst to catalytically treat organic pollutants, the organic pollutants can be quickly and thoroughly catalytically reduced within a short time, and thereby the organic pollutants are effectively degraded. The method disclosed by the invention has the advantages of simple process, easiness in operation, low treatment cost, high treatment efficiency, good treatment effect and the like, and has high application value and a wide application range.

Description

technical field

[0001] The invention belongs to the technical field of nano metal catalyst preparation, and relates to a method for treating organic pollutants by using chitosan-modified active coke to support nano-gold catalyst in situ.

[0002] technical background

[0003] Nitroaromatic compounds are a class of toxic and biodegradable organic pollutants, and are important raw materials and intermediate products in chemical production. With the development of the chemical industry, nitroaromatic compounds also enter the environment through various channels, polluting the environment and endangering human health. At the same time, aminophenol, the reduction product of nitroaromatic compounds, is an important chemical and pharmaceutical intermediate used in the synthesis of dyes, medicines, synthetic resins, surfactants and other chemical products. Azo dyes are compounds containing one or more azo bonds, are highly toxic and resistant to biodegradation, and are also an organ...
