ABSTRACT
The aim of our study was to investigate the effectiveness of Fenton and photo-Fenton processes for
removing anionic surfactants from aqueous solutions. The study was conducted using 200 mgL-1 linear
alkyl benzene Sulfonate (LAS) as a model of anionic surfactants. This study revealed that the mean removal
efficiency of LAS in Fenton and photo-Fenton at 20 minutes reaction time at 100 mgL-1 constant concentration
of hydrogen peroxide and 20 mgL-1 ferrous Iron were 20.16 and 22.47%, respectively. Meanwhile, LAS
removal efficiency (at 80 minutes reaction time for constant concentration of 800 mgL-1 hydrogen peroxide
and 120 mgL-1 ferrous ion) were 69.38 and 86.66%, respectively, which is consistent with the significant
increase in the rate of LAS removal efficiency with reaction time (P<0.05). In conclusion, anionic surfactants
removal was significantly correlated with reaction time by both methods, but showed less dependence on
H2O2 and Fe2+ concentrations.
