Environmental protection draws great attention worldwide due to the release of various harmful pollutants that represent risks or threats to animals and humans. Among these pollutants, endocrinedisrupting chemicals (EDCs) as environmental contaminants interfere with the normal hormonal functions in wildlife and humans. This study proposes multi-walled carbon nanotubes – (MWCNTs) pristine and oxidized, and weathered for one year in environmental conditions – as sorbents for bisphenol A (BPA) from aqueous solution. Kinetic and isotherm models are examined. Better sorption capacities are shown for the functionalized MWCNTs-COOH because of the two types of predominating interactions that take place: electrostatic and π-π interactions. The Langmuir isotherm model fit better than the Freundlich one, showing that the adsorption of BPA on MWCNTs is a monolayer adsorption on homogeneous surfaces.
