Abstract EN
The photocatalytic degradation of indigo carmine (IC) dye in the presence of titanium dioxide under different conditions was reported.
Several factors which interfere with the photodegradation efficiency as catalyst concentration, pH, initial concentration of dye, presence of inorganic anions, temperature, and the addition of hydrogen peroxide were studied under artificial irradiation with a 125 W mercury vapor lamp.
Additionally, the catalyst supported on glass spheres was used for the photocatalytic degradation of the dye present in several types of waters in a CPC solar pilot plant.
The photocatalytic products, carboxylic acids, and SO42- and NH4+ were followed during IC mineralization.
Formate, acetate, and oxalate were detected in real MWWTP secondary effluent.
The mineralization efficiency was of 42 and 21% using in suspension and supported TiO2, respectively.
In order to evaluate biological effects, Eisenia andrei earthworms were used as a model organism.
No significant difference (P>0.05) of weight was observed in the earthworm submitted to different concentrations of IC and its photoproducts.
The photocatalytic degradation of IC on TiO2 supported on glass spheres suffered strong influence of the water matrix; nevertheless the method has the enormous advantage that it eliminates the need for the final catalyst removal step, reducing therefore the cost of treatment.
