Scientists from Mainz and Aschaffenburg developed a method to protect the ozone layer from the damaging effects of the chlorofluorocarbon Freon 11
Sustainable and environmentally-friendly method of binding Freon 11
In their paper in the journal Global Challenges, the scientists from Mainz and Aschaffenburg describe a method of effectively binding both airborne and liquid phase Freon 11 using modified cyclic sugar molecules, i.e., a substance called methyl-substituted ?-cyclodextrin. This would prevent the release of the environmentally harmful foaming agent into the atmosphere, where it additionally impairs the stratosphere’s ability to protect against UV radiation. The process of Freon 11 binding is reversible and the adsorbent medium can be fully regenerated under controlled conditions. The recovered material can also be reused. This makes the process a sustainable and environmentally-friendly method of binding this extremely ozone-depleting substance, a method that can be readily employed when old refrigerators are scrapped, for example.
In addition, the research teams at Mainz and Aschaffenburg have been able to transfer this concept to an optical sensor device, making it possible to detect low concentrations of Freon 11 quickly and reliably.
