Nitrofurazone Removal from Water Enhanced by Coupling Photocatalysis and Biodegradation
(1) Background: Environmental contamination with antibiotics is particularly serious because the usual methods used in wastewater treatment plants turn out to be insufficient or ineffective. An interesting idea is to support natural biodegradation processes with physicochemical methods as well as wi...
