  • Abstract There are many products containing surfactants in our daily life; among the many surfactants used sodium dodecyl sulfate (SDS) is one of the most commonly used anionic surfactant. With the increasing amounts of surfactant in domestic and industrial wastewater, it will have a serious impact on our aquatic environment if the wastewater is not properly treated and directly discharged to rivers.
     In this study, the Fenton method was applied to treat surfactant SDS in wastewater. Degradation of SDS under different conditions was investigated to find the optimal conditions for SDS degradation and the experimental results were analyzed by kinetic models.
     The results showed that the optimal amount of Fe2+ was found to be 0.5 mM with 73% SDS removal ratio in 2 hours. The removal ratio of SDS increased with increasing amount of H2O2 up to 5 g/L dose and decreased with further increasing H2O2 dose. The removal ratio of SDS was found to be higher for lower initial SDS concentration or higher reaction temperature. The optimal SDS removal ratio was found to be 77% in 2 hours at pH 3. The commonly used pseudo first order kinetic model was not adequate to fit the kinetic data. The good fit of the kinetic data to a multi-step model suggests that the Fenton reaction of SDS degradation involves complicated reaction mechanism.
