Two different types of cobalt-based catalysts were synthesized and tested as Oxone®
activators in catalytic oxidation of model dye, tartrazine. First type of catalyst was cobalt
impregnated aluminum pillared montmorillonite, and the second one was cobalt-doped
alumina. Aluminum pillared montmorillonite was synthesized from Na-exchanged Wyoming
clay and impregnated with cobalt using incipient wetness impregnation method. Cobalt-doped
alumina catalysts were synthetized using the sol-gel method. Three calcination temperatures
were employed: 500 °C, 1000 °C and 1100 °C. The degradation of tartrazine was monitored
using Thermo Scientific Evolution 220 UV–Visible Spectrophotometer in the wavelength
range from 200–600 nm.In this wavelength range the monitoring of decolorization, along
with registering the emergence, followed by degradation,of detectable degradation products
was achieved. The effect of the different reaction parameters on decolorization and
degradation efficiency wa...s tested, including the influence of the mass of catalyst, reaction
temperature and initial pH. It was found that the increase of temperature and the mass of catalysts were beneficial for the reaction.All investigated catalysts were found to be very efficient in the Oxone® initiated tartrazine decolorization and degradation.
