A kind of kaolinite-humic acid composite colloid preparation method for adsorbing acetaminophen

Abstract

The invention discloses a preparation method of kaolinite-humic acid composite colloid for absorbing acetaminophen. The kaolinite-humic acid composite colloid is prepared by taking kaolinite and humic acid as a main raw material, mixing the humic acid colloid solution with quantified montmorillonite, and performing a series of post treatment steps with specific parameters. Through specific technical parameters, the kaolinite is organically compounded with humic acid together to obtain the absorbent material taking kaolinite as a wall material and the humic acid as the core material. The kaolinite-humic acid composite colloid has very high specific area and special charge property, and can provide enough absorbing site, thereby increasing the absorption capacity of the acetaminophen.

Description

technical field

[0001] The invention belongs to the field of functional materials, and in particular relates to a material for treating waste water containing antibiotics, in particular to a preparation method and application of a kaolinite-humic acid composite colloid for absorbing acetaminophen. Background technique

[0002] Acetaminophen (i.e. paracetamol) belongs to antipyretic and analgesic drugs, and it is one of the anti-inflammatory and pain-relieving drugs that are kept in the family. It is widely used. The toxicity of overdose may be manifested as kidney damage and acute liver failure. Poisonous compounds, if not handled properly and enter the environment, are very likely to form "pseudo-persistent" pollution, which in turn poses a great threat to human health and ecosystems. According to incomplete statistics, acetaminophen has been detected in the main water bodies of the Yangtze River Delta, Pearl River Delta, Liaohe River and Haihe River in my country. The sou...
