In this study, an effective composite material, manganese-modified magnetic dual-sludge biochar (Mn@MDSBC), was developed for the adsorption of ciprofloxacin hydrochloride (CIP). This prepared by means a simple one-pot method, which involved pyrolysis iron-based waterworks sludge (IBWS) and paper mill (PMS) loaded with manganese (Mn) under controlled conditions in nitrogen atmosphere. The synthesized Mn@MDSBC subjected to comprehensive suite characterization approaches, included N2 adsorption–desorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), photoelectron (XPS). Subsequently, static tests were conducted investigate how different factors, including initial solution pH, reaction time temperature, CIP concentration, ionic strength influence Mn@MDSBC. had maximum capacity 75.86 mg/g at pH 5, among values ranging from 3 9. pseudo-second order model provided best description process, while experimental data aligned more closely Langmuir equation than Freundlich model, indicating monolayer adsorption. process found be non-spontaneous exothermic according thermodynamic analysis. presence Cl− SO42− enhanced adsorption, PO43− weakened it. After five cycles reuse, experienced 17.17% loss capacity. primary mechanisms removal identified as physical chemical hydrogen bonding, π-π stacking interactions. summary, study underscores high efficiency material highlighting its potential application wastewater treatment processes.
