Removal of methylene blue From Aqueous Solution Using Lemon Peel - Fe3O4 Nanocomposite Adsorbent

Abstract

In this study, nanocomposite from the lemon peel was synthesized after precipitation nano iron oxides (LE-Fe3O4) by co-precipitation method and used as an important adsorbent in the adsorption process to remove the MB Dye from the aqueous solution in the batch study taking into account the parameters (pH, dose, initial concentration, and contact time). The optimum condition obtained from the experiment appears to be pH 8, 15mg\50ml dose, 50 ppm initial MB concentration, and 40 min contact time. Max adsorption capacity was 80 mg/g, and the adsorption experimental data best fitted with langmuir isotherm model indicating that the adsorption was monolayer.
