Effect of Synthesis Method and Reaction Conditions on Ciprofloxacin Adsorption from Aqueous Solutions by MoS_2 Materials

This study investigates the adsorption performance of MoS2 nanomaterials under various conditions for the removal of ciprofloxacin (CIP) from water.Antibiotics are essential for treating infections, but their persistence in water and the resulting antibiotic resistance pose environmental risks.CIP is commonly found in water systems, necessitating effective removal methods.MoS2, a material that has garnered significant attention in recent years, is widely used across various fields and shows promising characteristics as an adsorbent.In this experiment, the adsorption performance of commercial molybdenum disulfide was compared with hydrothermally synthesized MoS2 nanomaterials, with structural analysis conducted using XRD and SEM.The results demonstrated that the synthesized MoS2 nanomaterials, with smaller particle sizes, exhibited more stable and rapid CIP adsorption, fitting well with a pseudo-second-order kinetic model.These findings suggest that MoS2 nanomaterials are effective and stable adsorbents for CIP removal from water.
