Abstract
<p>In this work, catalysts were synthesized based on chemically modified clays through pillaring process with Al (III) and Fe (III) using commercial bentonite and acid-treated montomorillonite like KSF montmorillonite and K10 montmorillonite from Aldrich, as raw materials. The raw materials and chemically modified clays were characterized by: BET (Brunauer-Emmet-Teller) method and XRD (X-ray diffraction). Afterwards these catalysts were tested during wet oxidation with peroxides using phenol as target compound. Experimental results show that chemically modified clays with Fe(III) presented a higher catalytic activity in Fenton like processes than Al-Fe clays.</p>
Highlights
The urban distribution of qualitative water for human consumption, domestic activities and industrial use is a fundamental objective concerning the sustainability of life quality for the population
The catalytic activity of the pillared clays in the phenol oxidation reaction in diluted aqueous medium is represented by Fenton like reaction (Fe3+/H2O2) and is evaluated by catalytic coefficient considering the reaction of first order
According to the basal distance (d001) values obtained by X - ray diffraction (XRD) analysis, that are presented in Figure 1, Figure 2 and Figure 3, the incorporation of Fe+3 and Al+3 cations in the structure of clays type K10, KSF and Be-Na did not positively influence because the values of the basal distance of new structure are smaller than the basal distance of the raw clay
Summary
The urban distribution of qualitative water for human consumption, domestic activities and industrial use is a fundamental objective concerning the sustainability of life quality for the population. Among the catalysts used in Fenton (Fenton like) reactions the pillaring clays presented a high interest in the late years due to their special texture and catalytic properties. This catalyst confers a high catalytic activity for phenol conversion and it can be reused for many times, without losing its catalytic activity [5]. Catalysts were synthesized based on chemically modified clays through pillaring process with Fe (III) and Al (III) - Fe (III) Afterwards these catalysts were tested by wet oxidation with peroxides using phenol as target compound. Verifying the hypothesis that the reaction is of order 1, we observed that the value of the rate constant K increases with the decrease of the phenol concentration
