The increase of emerging water pollutants such as azithromycin (AZM) antibiotics in wastewater effluents poses a notable concern because they are nonbiodegradable and can lead to potential health risks. To address this, sodium lauryl sulfate-modified sweet potato peel (MSPP0 was investigated for its removal efficiency in AZM removal from aqueous solution. The SLS modification enhanced the surface morphology of the adsorbent as well as provided more functional groups which were confirmed by the SEM and FTIR analysis. Meanwhile, the pH point of zero charge of MSPP was determined to be 5.8. In batch adsorption study, a two-level full factorial design was employed to assess the effect of the different parameters. It was found out that the adsorbent dosage, initial concentration, and the pH solution all have a significant effect on the removal efficiency of AZM by MSPP. The best operating conditions that yielded the highest AZM percentage removal (78.4%) were 0.075 g L-1 for adsorbent dosage, 100 ppm for AZM initial concentration, and solution pH 4. The kinetic model that best described the experimental data was the Elovich model (R2=0.9813) which indicates that chemical interactions governed the mechanism of the adsorption process. On the other hand, the isotherm model that best fitted the AZM adsorption was determined to be the Freundlich model (R2=0.9956) which implies a multilayer adsorption on the system that is heterogeneous in nature. The maximum adsorption capacity of MSPP for AZM removal was found to be 1010 mg g-1, which is significantly higher than that of other adsorbents employed for AZM removal. This suggests that SLS-modified SPP is a very promising and cost-effective adsorbent that can be effectively utilized for the elimination of AZM from aqueous solutions. Sweet potato peels.
