In this work smectite pillared with mixture of aluminium and cobalt poly(hydroxo metal)
cations (Al,Co-PILC) was synthesized and tested as catalyst in degradation of food dye
tartrazine by peroxymonosulfate. The Al,Co-PILC was obtained using a common procedure
consisting of the following steps: grinding, sieving, Na exchange, intercalation, drying and
calcination. Co2+ to (Al3++Co2+) molar ratios in the pillaring solution was 10%. Catalytic tests
were carried out in a semibatch reactor under stirring and constant temperature maintained by
circulation of thermostatic fluid using Julabo MC 4 heating circulator. Initial dye
concentration was 50 ppm in the presence of excess of peroxymonosulfate. Decolorization of
tartrazine solution was monitored using UV-Vis spectrophotometry at max= 426 nm. The
influence of the mass of the catalyst and reaction temperature was investigated.
Catalyst mass and temperature increase were beneficial for dye degradation rate. The catalytic
process... at 30 ºC reached 97% for 120 min and besides decolorization included further
degradation of products of tartrazine oxidation. At 50 ºC complete decolorization occurred for
only 30 min. This work showed that application of smectite pillared with mixture of aluminium and cobalt poly(hydroxo metal) cations as peroxymonosulfate activators for
degradation of water pollutants is very promising.
