Cobalt-doped alumina catalyst was tested in peroxymonosulfate-induced degradation of two
textile dyes: anionic-Orange G (OG) and cationic-Basic Blue 41 (BB). Oxone®, mixed salt
containing peroxymonosulfate as an active component, was used as an oxidizing agent.
Catalytic tests were performed in a thermostated reactor equipped with a mechanical stirrer.
Dyes degradation was followed using a UV-Vis spectrophotometer. Characteristic peak
maximum in UV-Vis spectrum was identified at λ=478 nm for OG, and at λ=609 nm for BB.
Two OG concentrations were applied: 20 mg dm-3 and 50 mg dm-3. BB concentration was 20
mg dm-3 in all experiments. The reaction temperature was 30 ºC. Apart from simultaneous
dyes degradation, single-component solution degradation tests were also performed. Both
dyes were found to be degradable in single dyes systems, with OG showing a higher
degradation rate. When it comes to simultaneous degradation, it was noticed that the
degradation of the BB did not occu...r while OG was present in the system. This phenomenon
can probably be attributed to the difference in the molecular structure and charge of the
investigated dyes.
