Abstract

The invention discloses a method of utilizing a graphene oxide (GO) / eosin Y compound to photo-catalytically degrade beta-lactam type antibiotic in water. The composite material is prepared by bindinga dye (eosin Y) with GO through covalent bonds and has the advantages of GO such as strong adsorbing performance. At the same time, the photocatalytic performance of GO is greatly enhanced by the photosensitive dye. When the dye is illuminated, dye molecules are excited by light to generate electrons, which can reduce dissolved oxygen in a solution to generate strongly oxidative 1O2 and H2O2; and1O2 and H2O2 can oxidize and degrade beta-lactam type antibiotic adhered on the GO surface. The provided method has the characteristics of simple operation, rapidness, high efficiency, and large application range, and can utilize sunlight to process a water sample.

Description

technical field [0001] The invention relates to a method for photocatalytically degrading β-lactam antibiotics in water by a graphene oxide / eosin Y compound, which belongs to the field of environmental management. Background technique [0002] my country is the world's largest producer of APIs and a big country in the use of antibiotics. The production of APIs and the use of antibiotics will bring serious antibiotic pollution to environmental waters. Antibiotic pollution may induce and spread various types of antibiotic-resistant bacteria. It affects the human immune system, thereby threatening human health (Chen Fei. 2013. Preparation of magnetic surface imprinted composite photocatalyst and research on selective degradation of antibiotics [D]. Xi'an: Chang'an University.). At present, the methods used to remove β-lactam antibiotic pollutants mainly include physical and chemical methods, biological treatment methods, chlorination methods, and advanced oxidation treatment tec...
