“…5b that a maximum of catalytic activity was observed at a pH range of 2.77-7.87, where the complete oxidation of 4-CP was achieved within 1 h. The pH range was much wider than that not only in classical Fenton's reactions but also in Fenton-like reactions catalyzed by iron-based heterogeneous catalysts [22,27]. This strongly supported the view of Caudo et al [10] who considered that copper-based heterogeneous catalysts had a wider range of pH operations.…”

“…There are numerous works dedicated to the CWPO of phenol [3,14,16,21,22], while it was not the case for the CWPO of tartrazine. In most of the published papers dealing with CWPO of phenol it was shown that after 1 h of the reaction phenol degradation was similar or lower than the one obtained in this research, but after 2 h often exceeded the degradation efficiency of our system.…”

Al,Fe-pillared clay was synthesized from domestic clay from Bogovina according to a common procedure: grinding, sieving, Na exchange, pillaring, drying and calcination. Two synthesized samples differing only in calcining conditions were prepared. Phase composition and textural properties of the starting clay and synthesized pillared clays were characterized using X-ray diffraction and physisorption of nitrogen. Catalytic tests were performed using sample with better textural properties being the one submitted to milder calcining conditions. Catalytic wet peroxide oxidative degradation of aromatic compounds phenol and tartrazine on the synthesized catalyst was confirmed showing better efficiency in the case of tartrazine.

“…Zeolites [13][14][15][16][17], carbon materials [18,19], mesoporous and mixed oxides [20,21] and clays [12,[22][23][24][25][26] have been used as sup-ports of iron in the preparation of heterogeneous catalytic systems. In particular, zeolites containing transition metal ions have been shown to be promising solid-phase catalysts in the oxidation of a series of organic pollutants with hydrogen peroxide [27].…”

The degradation of Orange II dye (OII) by a heterogeneous Fenton-like process was studied using a catalyst with 5 wt.% of iron after ion-exchange in a Na-Y zeolite support. The catalyst was characterized by X-ray diffraction (XRD), N2 adsorption, atomic absorption spectroscopy and X-ray fluorescence (XRF). The effect of the initial concentrations of H2O2 and OII, pH and temperature on the degradation rate of OII was investigated by carrying out experiments in a batch reactor. The OII concentration histories (i.e., concentration evolution along reaction time) were described by a simple semi-empirical kinetic model, based on the Fermi's equation, which captures simultaneously the influence of all the reaction conditions with a few adjustable parameters. The adherence of the model to the data was remarkable, and the effect of the operating conditions on the obtained fitting parameters -apparent rate constant and transition timewas analyzed.2
