Abstract

The mineralization of surfactant by the Fenton and UV/Fenton advanced oxidation processes was studied. The surfactant considered in this work was secondary alkane sulfonate (SAS) as commercial product Hostapur SAS which is widely used for manufacturing of textile auxiliaries, household and industrial detergents. Experiments were conducted to examine the effect of concentration of ferrous sulfate (FeSO4), hydrogen peroxide (H2O2) and their molar ratio, pH, temperature and UV radiation on the extent and the rate of surfactant mineralization in water. Laboratory scale experiments showed that UV/Fenton was the most effective process. SAS with the initial concentration of 10 mg/l was mineralized 82 % by UV/ Fenton process in 120 minutes.
