This research has been done in graduate faculty of environment, university of Tehran, during the year 2018.The experiments were conducted in a batch reactor. The SS was obtained from the Esfahan Steel Company. X-ray diffraction (XRD) and field emission scanning electron microscope (FE-SEM) and energy dispersive spectroscopy (EDS) analysis were used to investigate the characteristics of the SS. The effects of SS dosage (0-5 g L<sup>-1<\/sup>), PS concentration ratio (1-5 mmol L<sup>-1<\/sup>), and reaction time (0-180 min) on the removal of MB was studied. The results showed that the Maximum removal efficiencies at optimize operational conditions (SS concentration 4 g L<sup>-1<\/sup>, PS concentration: 4 mmol L<sup>-1<\/sup> and reaction time: 45 min) was 84.76%. The addition of SS (4 g L<sup>-1<\/sup>) to PS led to about a \u00a07-times increase in removal rate constants of MB. The results confirmed the performance of (SS) as a (PS) activator for the \u00a0removal of MB from aqueous solution<em>.<\/em><\/span><\/p>\n<p><span style=\"font-family: 'Times New Roman', Times; font-size: 17px;\"><strong>Keywords:<\/strong> Steel slag (SS), Persulfate (PS), Methylene blue (MB), Removal.<\/span><\/p>\n<p><span style=\"font-family: 'Times New Roman', Times; font-size: 17px;\">Full paper in English: <a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/v10n1p23.pdf\">pdf<\/a><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Alaa Soubh * (1) and , Suleiman Mohammad (1) (1).
