Photo-assisted ozonation of cefuroxime with solar radiation in a CPC pilot plant. kinetic parameters determination

The combination of ozone and solar radiation can be considered an effective technology as advanced oxidation process, AOP, for addressing the removal of harmful contaminants of emerging concern in water. Cefuroxime is an example of an antibiotic whose presence may result in a problem if not convenie...

Cefuroxime is an example of an antibiotic whose presence may result in a problem if not conveniently removed from the water.
