Environmentally friendly chemistry: degradation and recovery technology of 1,2-diiodotetrafluoroethane

At the moment when the concept of sustainable development is deeply rooted in the hearts of the people, the research on the degradation and recovery technology of 1,2-diiodotetrafluoroethane is of great significance to reduce its potential impact on the environment and realize the recycling of resources. It is also a key measure to practice environment-friendly chemistry. 

The research on the degradation of 1,2-diiodotetrafluoroethane focuses on the development of efficient and green degradation methods. At present, photodegradation and biodegradation are the main research directions. Photodegradation excites 1,2-diiodotetrafluoroethane molecule by light at a specific wavelength, which breaks the chemical bond and gradually decomposes into small molecules. By screening efficient photocatalysts, such as titanium dioxide based catalysts and metal organic framework (MOF) materials, the photodegradation efficiency can be significantly improved and the degradation time can be shortened. Biodegradation converts 1,2-diiodotetrafluoroethane into harmless products by means of microbial metabolism. Scientists have improved the degradation ability of microorganisms to 1,2-diiodotetrafluoroethane by isolating and cultivating microbial strains with degradation ability, and optimizing the culture conditions, such as controlling temperature, pH value and nutrients, providing a new way for its environmentally friendly treatment. 

In terms of recycling technology, in order to realize resource recycling and reduce production costs, a variety of recycling methods are constantly explored and improved. The distillation method uses the difference of boiling points between 1,2-diiodotetrafluoroethane and impurities for separation and recovery. The operation is relatively simple, but the separation effect of impurities with simiLar boiling points is limited. In the extraction method, 1,2-diiodotetrafluoroethane was enriched and separated with suitable extractant, which could effectively improve the recovery purity. In addition, the adsorption method uses porous adsorption materials to adsorb and desorb 1,2- diiodotetrafluoroethane to realize its recycling. With the continuous innovation and optimization of degradation and recovery technology, 1,2-diiodotetrafluoroethane will better meet the requirements of environment-friendly chemistry, reduce the negative impact on the ecological environment while promoting the development of related industries, and realize the coordinated development of economy and environment.
