Macrocyclic nano cross-linking membrane based on Reso hydrocarbon and preparation method and application thereof

Abstract

The invention provides a macrocyclic nano cross-linking membrane based on Reso hydrocarbon and a preparation method and application thereof. The preparation method of the macrocyclic nano cross-linking membrane based on the Reso hydrocarbon comprises the steps that MC4RA and TC are used as a raw material, a macrocyclic nano cross-linking membrane pTC-MC4RA is prepared on the surface of a commercial drainage membrane or an organic membrane by adopting an interface cross-linking method, then, the pTC-MC4RA membrane is used as a basic framework, a small amount of HPC capable of generating singletoxygen is doped in an aqueous solution of the Reso hydrocarbon, through an interface cross-linking reaction among MC4RA, HPC and TC, a pTC-HPC-MC4RA membrane which is basically constant with a pTC-MC4RA structure is prepared, a germ experiment shows that the three-component cross-linking membrane can filter germs, can further kill the germs in situ in the light, and important significance is achieved for thoroughly removing the germs in drinking water. The preparation method of the macrocyclic nano cross-linking membrane based on the Reso hydrocarbon has the advantages that the preparation method is simple and easy to implement, use level costs of the Reso hydrocarbon and hypericin are low, and thus wide application prospects are achieved in the membrane filtering fields.

Description

technical field [0001] The invention relates to the preparation technology of nano cross-linked membranes, in particular to the preparation and characterization of nano cross-linked membranes based on macrocyclic host ratholane and its application in filtering dyes and sterilizing bacteria. Background technique [0002] Water treatment is closely related to our life. For example, dyes in industrial wastewater will cause great pollution to the environment, and bacteria in drinking water will cause harm to the human body. Therefore, for environmental protection and human health, it is necessary to remove dyes and Bacteria in drinking water is particularly important. Traditional energy-intensive separation technologies often bring heavy burdens to the economy and the environment during industrial production, while high-performance membrane separation technology has the advantages of simple process, low energy consumption, and no secondary pollution, and has become a kind of Ve...
