Removal of anionic surfactant sodium dodecyl sulfate from aqueous solutions by O3/UV/H2O2 advanced oxidation process: Process optimization with response surface methodology approach
This study investigates the removal of sodium dodecyl sulfate (SDS) by O3/UV/H2O2 process. Response surface methodology based on central composite design was used to assess the effects of process parameters including initial pH, H2O2 concentration, ozone dosage and reaction time on SDS removal.
