Abstract :
Perfluorooctane sulfonate (PFOS) has increasingly attracted global concerns in recent years and has also been proposed as the candidates of persistent organic pollutants due to their world-wide distribution, environmental persistence and bioaccumulation potential. The adsorption mechanism of PFOS from aqueous solutions onto granular activated carbon (GAC) was investigated. The adsorption reaction obtains equilibrium within 180 min and the maximum PFOS removal tended to be 99%. And the results of regression to the experimental data show that t the adsorption of PFOA onto the GAC was mainly governed by particle diffusion.
