If antibiotic residues in the environment could be eliminated or reduced, it could contribute to minimizing antibiotic resistance. Towards this objective, water containing ciprofloxacin was treated by sunlight-assisted photocatalysis using Fe- doped ZnO nanoparticles for assessing the degradation potential of this system. Parameters like pH, temperature, catalytic dosage were assessed for the optimum performance of the system. To evaluate degradation of ciprofloxacin, both spectrophotometric as well as microbiological (loss of antibiotic activity) methods were employed. 100 mg\/L Fe-doped ZnO nanoparticle catalyst and sunlight intensity of 120,000\u2013135,000 lux system gave optimum performance at pH 9 at 30 \u00b0C and 40 \u00b0C. Under these conditions spectrophotometric analysis showed complete degradation of ciprofloxacin (10 mg\/L) at 210 min. Microbiological studies showed loss of antibacterial activity of the photocatalytically treated ciprofloxacin-containing water against Staphylococcus aureus (108 CFU) in 60 min and for Escherichia coli (108 CFU) in 75 min. The developed system, thus possess a potential for treatment of antibiotic contaminated waters for eliminating\/reducing antibiotic residues from environment.<\/jats:p>","DOI":"10.3390\/ijerph15112440","type":"journal-article","created":{"date-parts":[[2018,11,1]],"date-time":"2018-11-01T11:31:47Z","timestamp":1541071907000},"page":"2440","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":110,"title":["Sunlight Assisted Photocatalytic Degradation of Ciprofloxacin in Water Using Fe Doped ZnO Nanoparticles for Potential Public Health Applications"],"prefix":"10.3390","volume":"15","author":[{"given":"Sourav","family":"Das","sequence":"first","affiliation":[{"name":"School of Biotechnology, Kalinga Institute of Industrial Technology (KIIT), Bhubaneswar 751024, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soumen","family":"Ghosh","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Kalinga Institute of Industrial Technology (KIIT), Bhubaneswar 751024, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ananyo","family":"Misra","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Kalinga Institute of Industrial Technology (KIIT), Bhubaneswar 751024, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0731-1680","authenticated-orcid":false,"given":"Ashok","family":"Tamhankar","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Kalinga Institute of Industrial Technology (KIIT), Bhubaneswar 751024, India"},{"name":"Department of Public Health Sciences, Karolinska Institutet, SE 17177 Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amrita","family":"Mishra","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Kalinga Institute of Industrial Technology (KIIT), Bhubaneswar 751024, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6525-1861","authenticated-orcid":false,"given":"Cecilia","family":"Lundborg","sequence":"additional","affiliation":[{"name":"Department of Public Health Sciences, Karolinska Institutet, SE 17177 Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suraj","family":"Tripathy","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Kalinga Institute of Industrial Technology (KIIT), Bhubaneswar 751024, India"},{"name":"School of Chemical Technology, Kalinga Institute of Industrial Technology (KIIT), Bhubaneswar 751024, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"j2440","DOI":"10.1136\/bmj.j2440","article-title":"Antibiotic residues in the environment of South East Asia","volume":"358","author":"Lundborg","year":"2017","journal-title":"BMJ"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1038\/nrmicro727","article-title":"Opinion\u2014Anti-infectives: Where will new antibiotics come from?","volume":"1","author":"Walsh","year":"2003","journal-title":"Nat.
