Photocatalytic Degradation of Some Antibiotics in Aqueous Solution
Antibiotics are emerging contaminants in the aquatic environment because of their adverse effects on aquatic life and humans. Antibiotics wastewater has high COD and very low BOD5, and hence is difficult to treat biologically. The objective of this research was to study the feasibility of using the...
