Abstract
Antibiotic resistance is one of the most alarming problems today. Therefore, composite membranes have been widely applied for the removal of antibiotics from water. PVA/Agarose/Maltodextrin films have been synthesized by casting with various component ratios. They were evaluated for characteristics through moisture, solubility, expansion, and BET results. The results showed that PVA/Agarose/Maltodextrin films exhibited the best viability in the aquatic environment through low solubility (68.88% ± 0.03), high swelling (431.77% ± 5.89) and pore volume (0.034969 cm³/g). The adsorption capacity of PVA/Agarose/Maltodextrin was tested for several antibiotics such as Ciprofloxacin, Tetracycline, Oxy-Tetracycline, and Chloramphenicol. The results showed that Ciprofloxacin was removed by the PVA/Agarose/Maltodextrin films better than other antibiotics. The highest antibiotic adsorption was obtained at 20 min, temperature of 30 °C, dosage of 2 g/L, pH 6, and antibiotic concentration of 40 mg/L. Ciprofloxacin adsorption was predicted through adsorption kinetic and isothermal models. The compatibility of the Pseudo First Order kinetic and Dubinin-Radushkevich isothermal has shown that adsorption takes place according to a physical adsorption mechanism with electrostatic interactions on the surface of the material. The maximum adsorption capacity recorded at 4.48 mg/g based on the Dubinin-Radushkevich isothermal.
