Results show that O3 process, which has formerly been considered insufficient as a sole treatment for such wastewaters, could be a viable treatment for the degradation of 1,4-dioxane at the adequate operation conditions. The treatment of both synthetic solution of 1,4-dioxane and industrial wastewaters, containing 1,4-dioxane and 2-methyl-1,3-dioxolane (MDO), showed that about 90% of chemical oxygen demand can be removed and almost a total removal of 1,4-dioxane and MDO is reached by O3 at optimal process conditions. Data from on-line Fourier transform infrared spectroscopy provides a good insight to its different decomposition routes that eventually determine the viability of degrading this toxic and hazardous compound from industrial waters. The degradation at pH>9 occurs faster through the formation of ethylene glycol as a primary intermediate; whereas the decomposition in acidic conditions (pH<5.7) consists in the formation and slower degradation of ethylene glycol diformate. eng Removal of 1,4-dioxane from industrial wastewaters: routes of decomposition under different operational conditions to determine the ozone oxidation capacity. journal article URL https://docta.ucm.es/bitstreams/279c743a-2cd4-42e7-bc7d-e9539d25b6ed/download File MD5 66433ca4c0efef55c664119f8f5a650f 356756 application/pdf Removal_of_1,4-dioxane_from_industrial_wastewaters.pdf URL https://docta.ucm.es/bitstreams/2b73a943-5653-4803-8a2c-83b9a16ff99f/download File MD5 3db11ea3819140fbea73f91fe62e394c 46657 text/plain Removal of 1,4-dioxane from industrial wastewaters_Barndok_2014.pdf.txt URL https://docta.ucm.es/bitstreams/0bb1ee53-c67a-4b07-a19a-608b3d86d40c/download File MD5 3db11ea3819140fbea73f91fe62e394c 46657 text/plain Removal_of_1,4-dioxane_from_industrial_wastewaters.pdf.txt
