Resumen:
Iron
pillared clay (Fe-PILC) was prepared from a montmorillonite and was
characterized by scanning electron microscopy, X-ray fluorescence and nitrogen
adsorption-desorption isotherm. Fe- PILC catalytic activity was evaluated in
photo-Fenton processes applied to the degradation of 2-clorophenol. Different
catalyst loads were assays. The Fe-PILC allowed almost complete degradation of
the contaminant. An increase in the contaminant degradation rate was observed,
following leaching of iron during catalytic assays, which suggest the existence
of a homogeneous photo-Fenton mechanism. The catalytic performance of the Fe- PILC
was compared with that for goethite and zero valent iron nanoparticles.
Differences were found regarding the achieved degradation levels, the
efficiency in oxidant consumption and the extension of iron leaching.
