Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...
