“…The phenol oxidation, as observed in the experimental designing studies (Table 3), depends strongly on the experimental conditions; for example, for the conventional Fenton reaction, the concentration of Fe(II) shows the strongest influence on the degradation process, followed by pH, both consistent with previously reported results [31]. The phenol degradation was higher (98.0%) when the variables were: [Fe 2+ ] = 8.9 × ] were at their highest level and pH at its lowest.…”

“…The ligand TBMA was synthesized as described in the literature [31,[38][39]. A mixture of nitrilotriacetic acid (0.02 mol, 3.82 g) and 1,2-diaminobenzene (0.06 mol, 6.49 g) was refluxed for 24 h in hydrochloric acid (50 mL, 6.0 mol L -1 ) .…”

“…The resulting solution was allowed to cool and the green crystals obtained were collected and washed with hydrochloric acid (2.0 mol L -1 ). The free base was isolated when the hydrochloride of the compound in water was neutralized with ammonium hydroxide (20%), then it was re-crystallized from aqueous ethanol and dried over P [31,[36][37][38][39][40].…”

The efficiency of phenol degradation by the iron complexes ([Fe(TBMA)Cl3∙3H2O] and [Fe(terpy)Cl2]) is compared with that of the Fenton reaction. The results show that although the Fenton reaction efficiently oxidizes phenol at low pH’s, the Fenton modified reagents (iron complexes/H2O2) effectively oxidize phenol at neutral pH. Besides, the factorial designing study is performed by considering three independent variables: (i) [Fe] (A), (ii) pH (B), and (iii) [H2O2] (C). For the Fenton reaction, the normal probability plot reveals that two factors, such as concentration of Fe2+ and interaction{[H2O2]∙pH} have considerable influence on the phenol oxidation; in the normal probability plot of the complexes, factors C (concentration of H2O2) and AC {[Fe]∙[H2O2]} have an effect on the oxidation of the phenol by [Fe(terpy)Cl2]/H2O2, while for [Fe(TBMA)Cl3∙3H2O], factors B and AC significantly influence the degradation. Of both iron complexes, [Fe(TBMA)Cl3∙3H2O]/H2O2 is an excellent oxidant, showing a good response at pH 7.0.
