Using photoactivated acetone for the degradation of Chlorazol Black in aqueous solutions: Impact of mineral and organic additives.

This study examined the effect of different mineral and organic additives on the degradation of Chlorazol Black (CB, 25.5 μM) in aqueous media by UV/acetone process. Initially, it was found that acetone (50 mM)-assisted UV irradiation accelerated the CB removal within 30 min to 98% against 34% for the sole UV, presumably due to the implication of methyl radicals in the degradation process as confirmed by O saturation and nitrite addition (as CH-specific scavengers).

Efficient degradation method of emerging organic pollutants in marine environment using UV/periodate process: Case of chlorazol black.

Sea has historically been subject to high anthropogenic pressures of direct and indirect loads of emerging organic pollutants (EOPs) from intensive industrial and agricultural activities. Photoactivated periodate (UV/IO) is an innovative oxidation technique that was never tested in seawater as pollutants matrix. In this work, we attempted to investigate the treatment of seawater contaminated with chlorazol black (CB) dye, as a model of EOPs, using photoactivated periodate process.
