Abstract

This research explores the adsorption of ciprofloxacin (CIP) from aqueous solutions using banana peel (BP) as an adsorbent. The goals include figuring out the removal efficiency under various conditions, characterizing BP and figuring out the isotherms and adsorption kinetics. According to the study, CIP's adsorption onto BP rose with increasing agitation rate, adsorbent dosage, and contact time. The adsorption process adhered to the Freundlich isotherm and followed the Pseudo-Second Order kinetic model, showing optimal effectiveness at pH levels above 4. The maximum CIP adsorption capacity by BP was 37.037 mg/g. SEM and AFM analyses verified surface changes in BP before and after adsorption, while the FTIR study suggested functional group involvement in the CIP-BP interaction. The significant factors that mainly contributes to the adsorption process was determined by Plackett-Burman Design, and the optimized condition equation was determined by Response Surface Methodology. BP shows great potential as an eco-friendly and cost-effective adsorbent for the removal of CIP from water, and additional modifications could further enhance both its adsorption capacity and practical utility.
