This study investigates the removal of the antibiotic ciprofloxacin (CIP) from contaminated water using Electric Arc Furnace Dust (EAFD). Environmental contamination by antibiotics can adversely affect the environment, especially living organisms. Such contamination </span>contributes to the development<span lang="EN-GB" style="color:black"> of microbial resistance to drugs and hinders the treatment of diseases using established antibiotics. </span><br> <b><span style="color:black">Methods:</span></b><span style="color:black"> Batch experiments were designed to evaluate the effects of initial ciprofloxacin concentrations (1-100 mg L^-1), solution pH (1-11), and amount of adsorbent (0.5-15 g). </span><br> <b><span style="color:black">Results: </span></b><span style="color:black">The<b> </b>results revealed that optimal conditions for removing ciprofloxacin from </span><span lang="EN-GB" style="color:black">contaminated water were achieved at an</span><span style="color:black"> initial CIP concentration of 10 mg L^-1 (50 mL), with a pH of 7 and a yield of 83 &plusmn; 5%, using 5 g of EAFD adsorbent.<b> </b>The pseudo-second-order and Temkin models were more consistent in predicting the kinetics and isotherms of the adsorption process, respectively.</span><br> <b><span style="color:black">Conclusion: </span></b><span style="color:black">The findings of this research demonstrate that EAFD is an effective adsorbent for removing CIP from </span><span lang="EN-GB" style="color:black">contaminated water.</span><span style="color:black"> Furthermore, this approach </span>concurrently addresses<span style="color:black"> two critical issues: CIP contamination and EAFD pollution.</span></span></span></span></div> Water treatment, Removal, Pharmaceutical residues, EAFD, Contamination, 94 102 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-122-9&slc_lang=en&sid=1 Arezoo Mehdikhani Arezoo.Mhdkh@gmai.com 100319475328460015613 100319475328460015613 No Environmental Science Research Laboratory, Department of Environmental Science, Faculty of Science, University of Zanjan, Zanjan, Iran.
