This study presents the synthesis of a biobased hydrogel composite (CC-PANI) using nanofibrous cellulose and polyaniline via in situ polymerization, designed as a biodegradable and non-toxic adsorbent for the efficient removal of rifampicin, a model antibiotic micropollutant, from aqueous solutions. Comprehensive characterization revealed significant physicochemical modifications in the composite, including enhanced surface morphology and porosity. Response surface methodology was employed to optimize critical parameters, achieving a maximum removal efficiency under 30 mg/L initial drug concentration, 20 mg adsorbent dosage, pH 7.0, and 55 degrees C. Adsorption kinetics, thermodynamics, and isotherm models confirmed CC-PANI's superior performance, with a Langmuir adsorption capacity of 117.02 mg/g. Reusability studies showed consistent performance, maintaining over 90 % removal efficiency across six adsorption-desorption cycles. These findings highlight the potential of CC-PANI as an innovative, sustainable, and cost-effective solution for micropollutant removal, significantly contributing to wastewater treatment technologies and environmental sustainability.
