Abstract

Because of the extensive usage of antibiotics, especially azithromycin, they are persistent in aquatic ecosystems, which presents dangers to the environment and public health. This study uses a batch experimental approach to examine the effectiveness of azithromycin removal from wastewater. Numerous factors affecting the adsorption process were methodically investigated, including contact time, initial drug concentration, pH, temperature, and adsorbent dosage. FTIR and SEM techniques were used to characterize the adsorbent. Curry neem bark's effectiveness as a budget-friendly adsorbent for eliminating azithromycin was assessed. The findings demonstrated that adsorption fit the Langmuir isotherm model well and followed pseudo-second-order kinetics, suggesting monolayer adsorption. The best removal effectiveness (up to 78%) was obtained at pH 5 with an adsorbent dosage of 0.12 g and a contact period of 60 minutes. In order to reduce pharmaceutical contamination in water bodies, this study shows that batch adsorption is a practical and effective technique for extracting azithromycin from wastewater.
