on four different analytical techniques: colorimetry (CIE<br />
L*a*b*), optical microscopy (OM) with visible and<br />
fluorescence light, atomic force microscopy (AFM) and<br />
scanning electron microscopy (SEM) was applied. The<br />
combinations of these techniques allowed an extensive and<br />
complete view of the surface material and its<br />
characteristics/behavior. Going to a nano-scale with the use<br />
of AFM proved to be of major importance to achieve a new<br />
further level of information; at the same time the conclusions<br />
were easily extrapolated to a larger scale.<br />
The new formulations and the non-invasive multi-technique<br />
methodology we propose in this work can be applied in<br />
conservation-restoration practice but further experiments<br />
are required to optimize the parameters of the application<br />
and to validate it on real art objects.<br />

Description<br />
Catalytic wet hydrogen peroxide oxidation (CWPO) is one of the<br />
most promising advanced oxidation processes, for the<br />
degradation of priority organic pollutants. Mixed Al-Cu pillared<br />
clays (AlCu PILCs) displays both good catalytic activity and<br />
high stability. The aims of this research was to study the CWPO<br />
of 4-chlorophenol over an AlCu PILCs prepared from<br />
indigeneous clay and compare it with catalysts prepared from<br />
reference materials. The pillaring process was successful for all<br />
the clays, as indicated by the increase in d 001 basal space (XRD)<br />
and in the surface area (BET nitrogen adsorption/desorption<br />
isotherms). The catalysts were very active allowing complete<br />
elimination of 4-chlorophenol and a significant reduction of<br />
chemical oxygen demand values (COD). The Romanian<br />
montmorillonite from Valea Chioarului can be successfully used<br />
for the preparation of AlCu PILCs, giving catalysts with<br />
activities comparable with those obtained from reference<br />
materials.<br />
