Detection and degradation technology of environmental persistent trifluoromethyl pollutants
With the wide application of trifluoromethyl (-cf ₃) compounds in industry and life, the problem of persistent trifluoromethyl pollutants (such as perfluorinated and polyfluoroalkyl substances, PFAS) in the environment has attracted increasing attention. These pollutants have environmental persistence, bioaccumulation and potential toxicity, and pose a threat to the ecological environment and human health. Therefore, the research of efficient detection and degradation technology is very important.
In terms of detection technology, high sensitivity analysis methods are emerging. Liquid chromatography tandem mass spectrometry (LC - MS/MS) has become the main means of detecting PFAS in the environment with its high resolution and high sensitivity. This method can accurately determine the content and composition of trace PFAS in different environmental media (such as water, soil, biological samples). In addition, the rapid detection technology based on the principle of immunoassay has also made important progress. Through the preparation of specific antibodies, the rapid and on-site detection of PFAS is realized, which provides a convenient tool for environmental monitoring.
In the field of degradation technology, advanced oxidation, photocatalytic degradation and biodegradation are the key research directions. The advanced oxidation method can degrade pollutants by generating strong oxidative free radicals (such as hydroxyl free radicals) and destroying the carbon Fluorine bond of PFAS. Photocatalytic degradation uses electron hole pairs generated by Semiconductor Photocatalysts under light to initiate the oxidative decomposition of PFAS. In recent years, biodegradation technology has also shown potential. By screening and cultivating microbial strains that can degrade PFAS, pollutants can be transformed into harmless substances by microbial metabolism. With the continuous innovation and improvement of detection and degradation technology, it will provide effective solutions to solve the problem of persistent trifluoromethyl pollutants in the environment.
