Graphene Oxide Derived from Cassava Peel as a Potential Adsorbent for Tetracycline Removal from Aqueous Environment
Summary
Researchers synthesized graphene oxide from cassava peel using a modified Hummers technique and evaluated its performance as an adsorbent for tetracycline removal from water. Optimal conditions — 20 mg adsorbent, 10 ppm antibiotic concentration, pH 5, and 10 minutes contact time — demonstrated effective tetracycline removal, suggesting agricultural waste-derived graphene oxide as a low-cost approach to antibiotic water contamination.
Due to the increase in bacterial resistance, the presence of antibiotic residues in ambient water is becoming a serious problem. In order to stop antibiotic-related water contamination, graphene oxide has been extensively employed as an advanced adsorbent. In this study, cassava peel was utilized to create graphene oxide, which was then applied as an adsorbent to remove tetracycline. The modified Hummers technique was used to produce graphene oxide, along with an oxidizing agent. Studies have been done on graphene oxide characterization and adsorption process optimization. According to the study, tetracycline removal was best accomplished under settings that included an adsorbent mass of 20 mg, an antibiotic concentration of 10 ppm, a pH of 5, and a contact period of 10 minutes. The adsorbent substance has shown promise in removing tetracycline from aqueous environments.
