Highly Effective Removal of Moxifloxacin from Aqueous Solutions Using Graphene Oxide Functionalized with Sodium Dodecyl Sulfate

ACS Sustainable Resource Management, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 2, 2025

In this study, sodium dodecyl sulfate modified graphene oxide (GO-SDS) was prepared as an adsorbent to remove moxifloxacin (MFX) from aqueous solution. Transmission electron microscopic (TEM) and scanning (SEM) images showed that SDS decreases the aggregation of GO surface, which significantly increased surface area interlayer distance between successive layers GO-SDS. Adsorption studies demonstrated 98% MFX removed by GO-SDS within 15 min at pH 5.8, while dosage 37.5 mg L–1. The adsorption kinetics followed pseudo-second order linear model, Langmuir isotherm model fitted data better than Freundlich model. values ΔH ΔS obtained thermodynamic were +5.603 kJ mol–1 +2.114 K–1, respectively, indicating process is endothermic spontaneous. Furthermore, satisfactory reusability revealed it could be effective for removal
