Application of Induction Furnace Dust as an Adsorbent for the Removal of Ciprofloxacin from Contaminated Water

Background:The high production and consumption of various drugs have resulted in severe environmental problems.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 contributes to the development of microbial resistance to drugs and hinders the treatment of diseases using established antibiotics.Methods: 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). Results:The results revealed that optimal conditions for removing ciprofloxacin from contaminated water were achieved at an initial CIP concentration of 10 mg L -1 (50 mL), with a pH of 7 and a yield of 83 5%, using 5 g of EAFD adsorbent.The pseudo-secondorder and Temkin models were more consistent in predicting the kinetics and isotherms of the adsorption process, respectively. Conclusion:The findings of this research demonstrate that EAFD is an effective adsorbent for removing CIP from contaminated water.Furthermore, this approach concurrently addresses two critical issues: CIP contamination and EAFD pollution.
