ABSTRACT
In this study, flaxseed mucilage (FSM) has been used as a green coagulant in the pretreatment stage of a combined process for the removal of an anionic surfactant, sodium dodecyl sulfate (SDS). In the post-treatment stage, heterogeneous photo-Fenton-like oxidation using MnFe2O4 nanocatalyst was applied to remove the remained SDS. Using response surface methodological approach, optimum condition in the coagulation process was obtained at pH 7.0, FSM dose of 100â¯mgâ¯L-1 and 30â¯min. In the photo-Fenton oxidation process, complete SDS removal was achieved using 76â¯mg of the nanocatalyst, 1.07â¯mL of H2O2 at 17â¯min. Application of the combined process on the real wastewater samples indicates that the proposed method can be used effectively for the treatment of industrial effluents containing surfactants.
