Abstract

Background and objectives: BISPHENOL A (BPA) is an endocrine disrupting chemical that releases to the environment through effluents of its producing factory, pulp and paper mill factories, and plastics industry. The purpose of this study was to investigate ADSORPTION ISOTHERMs of removing BPA from AQUEOUS SOLUTIONs using SINGLE WALLED CARBON NANOTUBEs (SWCNTs).Materials and methods: This study was an empirical investigation. Our experiments were conducted discontinuously using 50 mL of sample in each test. The variables of this study were the contact time (5, 15, 30, 60, 90, 120 min), the initial concentration of BPA (2, 5, 20, 50 mg/L), and pH (3, 5, 6, 9, 11). The concentrations of BPA were measured using UV-Vis spectrophotometer.Results: The maximum adsorption capacity was found to be 71.42 mg/g. The results of our experiments showed that maximum adsorption capacity at equilibrium was achieved at t=60 min and pH=9. Moreover, increasing the initial concentration is associated with an increase in adsorption capacity until it becomes constant.Conclusion: The BPA adsorption on SWCNT follows Freundlich-Langmuir isotherm.
