Özet
In the present study the adsorption of naproxen sodium onto activated carbons (BK4 obtained from white polymeric waste and SK4 obtained from black polymeric waste) was investigated by calculating the parameters of pH contact time the concentration of naproxen sodium and the temperature The adsorption data of naproxen sodium onto activated carbon follows the Langmuir isotherm model and its kinetic processes were described by various kinetic adsorption models It was determined that the pseudo-second-order model was the best choice among all the available kinetic models to describe the adsorption behaviour of naproxen sodium onto activated carbon During the present study the intra-particle diffusion rate constant the external mass transfer coefficient and the film and pore diffusion coefficient were evaluated at various temperatures In addition the thermodynamic parameters of the adsorption of naproxen sodium onto activated carbon were also calculated Crown Copyright (C) 2010 Published by Elsevier B V All rights reserved
