Thecompound prepared by the method provided by the invention has good stability to water and good adsorption ability to drug pollutants, and also has certain desorption ability and recycling ability, and therefore has potential application in adsorption of drug residue in environmental water.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical pollutant adsorbents, in particular to a preparation method and application of a copper metal organic framework compound. Background technique [0002] With the advancement of society and the development of the pharmaceutical industry, in recent decades, more and more water systems have detected residues of various drugs, drug metabolites and pharmaceutical excipients. Drugs mainly include antibiotics, hormones, anti-inflammatory drugs, etc., while pharmaceutical excipients mainly include solubilizers, co-solvents, emulsifiers, colorants, adhesives, etc. These drugs, drug metabolites and pharmaceutical excipients have complex structures and diverse components, and they degrade slowly under natural conditions. At the same time, with the continuous production and use of people, more and more drugs, drug metabolites and pharmaceutical excipients are discharged into the water body. Persistent...
