Application Of Chemometrics Methods To Resolve Intermediates Formed During Photocatalytic Degradation Of Methyl Orange

The efficiency of two catalysts (TiO2 and TiO2 supported on zeolite) for the photocatalyticrndegradation of MO dye has been evaluated by means of chemometrics methods by using UV/Visrnspectroscopic data of the degraded dye. This study provides clear evidence about the catalyticrnefficiency of the two catalysts under UV light irradiation for the degradation of MO dye. MCRALSrnstatistical method was used for the catalytic efficiency evaluation. MO photodegradation atrnpH 3 using TiO2 catalyst shows better decolorization efficiency than at pH 8 and using TiO2rnsupported on zeolite catalyst but the kinetics of MO degradation is quicker at pH 8. For therndegradation using TiO2 at pH = 3, after 150 min of photocatalysis reaction, the species thatrnshows the concentration profile of MO disappears. The kinetics data reveals that the reaction isrnfirst order with respect methyl orange in any case.rnKey words: Chemometrics, Photodegradation, MCR-ALS, MO and TiO2
