Comparison of advanced oxidation processes for the removal of trimethoprim and 5-fluorouracil
Two pharmaceuticals, trimethoprim (TRIM), an antibiotic, and 5-fluorouracil (5-FU), a widely used cytostatic, were applied as target substances to compare the efficiency of various AOPs, such as UV (254 nm), UV/VUV (254/185 nm) photolysis, ozonation, and O3/UV process. Opposite that, there is no sig...

| 520 | 3 | |a Two pharmaceuticals, trimethoprim (TRIM), an antibiotic, and 5-fluorouracil (5-FU), a widely used cytostatic, were applied as target substances to compare the efficiency of various AOPs, such as UV (254 nm), UV/VUV (254/185 nm) photolysis, ozonation, and O3/UV process. Opposite that, there is no significant difference between the molar absorbance of target substances; TRIM transformed very slowly, while 5-FU degradation was fast in 254 nm radiated solutions. The low-intensity 185 nm VUV photons highly increased the transformation and mineralization rate of both components. Ozonation was highly effective for eliminating both compounds. However, the mineralization was limited due to the formation products being resistant to ozone. The O3/UV process primarily increased the mineralization rate, but no significant change in the transformation rates was observed. Comparing the individual methods in terms of energy consumption, the O3, and O3/UV combination was the most effective for both compounds. The effect of biologically treated wastewater as a real matrix significantly reduced the transformation rate in the case of UV/VUV photolysis, while the matrix effect was moderated for O3/UV and negligible or even positive for ozonation. | |
