Problems solved by technology

Among them, the oxidant oxidation method, wet oxidation method (WAO), biological filter method, etc. are suitable for treating heavily polluted and highly toxic wastewater. This type of method is a non-secondary pollution, very effective and promising water treatment method, but the cost is relatively high. high
Among them, the safety performance of the flocculation method is not ideal, and the adsorption method has attracted the attention of more and more relevant scientific and technological workers because of its simple operation steps, low price and easy availability, and the high safety performance of the treatment process.

Abstract

The invention relates to a polymer material for adsorbing antibiotics, a preparation method and an application thereof. The polymer material is a polyaniline derivative polymer material obtained by reacting certain amount of acid solutions of aniline and ortho-aminophenol under the action of an initiator to generate solid precipitates, and performing separation, washing, vacuum drying, and grinding of the precipitates. The polyaniline derivative polymer material of the invention is used for adsorbing antibiotic pollutants such as tetracycline, terramycin, aureomycin, norfloxacin and the like, and has better adsorptive property than conventional adsorption materials. The polyaniline derivative has a maximum adsorption capacity of 127.14 mg / g, and the preparation method of the invention is simple in steps, low in cost, and convenient to operate. The polymer material and the preparation method of the invention have wide application prospects in the field of antibiotic treatment for sewage.

Description

technical field [0001] The invention relates to a polymer material for adsorbing antibiotics and its preparation method and application, belonging to the technical field of polymer composite materials, in particular to the preparation of a polyaniline derivative adsorbent for adsorbing antibiotics, and the modified polyaniline adsorbent used in Adsorption of antibiotics in pharmaceutical factory wastewater. Background technique [0002] With the rapid development of science and technology, antibiotics are widely used in people's life and production, and there are problems of abuse and illegal use. It is a common understanding of human beings that the abuse of antibiotics leads to the health risks of drug resistance. A large number of antibiotics end up in the environment and become one of the new important pollutants in the environment. Antibiotic industrial wastewater is a kind of high-concentration organic wastewater with high chroma, refractory degradation and high biolo...
