Flores Jayanthi Narayanan Hilda Calderón Thangarasu Pandiyan Multidisciplinaria (Ciencias Naturales y Exactas) iron complexes factorial design phenol oxidation Modified Fenton reagent 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 designingstudy 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 phenoloxidation; 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 anAC 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. 2013 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47527856005 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.2 Vol.57 |
