JAUE2022-113: Exploration of Molecularly Imprinted Membrane for Ciprofloxacin Filtration

Abstract

Ciprofloxacin (CFX), as a representative synthetic fluoroquinolone antibiotic, has been widely used in medical, animal husbandry and aquaculture industries, which leads to the generation of many wastewaters containing CFX. Due to the complexity of sewage components, conventional treatment methods are easy to lead to incomplete CFX treatment. Therefore, it is necessary to establish an efficient and selective removal technology directly acting on CFX before the treatment of other pollutants. Molecularly Imprinted Membranes (MIMs) are a kind of specific separation membranes which are coupled with membrane separation technology and MIM technology. The specific recognition and adsorption of Molecularly Imprinted sites on membrane surfaces and pore walls are used to achieve selective separation of specific components. The basic principle and mass transport mechanism of molecular technology were studied to explore the feasibility of its application in CFX removal in this paper, and finally the problem of easy contamination in the working process of MIMs was found. Therefore, the study on improving the anti-fouling capacity of MIMs will be of great significance for the future use of MIMs to remove CFX in water and will be our focus in the future research direction.
