Peroxymonosulfate-assisted photocatalytic degradation of artificial sweeteners in water

Abstrakt

In the present study, peroxymonosulfate (PMS) activation was proposed for efficient photocatalytic degradation of aspartame, acesulfame, saccharin, and cyclamate - artificial sweeteners frequently present in wastewaters and surface waters worldwide. The TiO2 nanosheets with exposed {0 0 1} facets were synthesised using the fluorine-free lyophilisation technique as a green concept for the synthesis and used for the photodegradation of selected sweeteners not susceptible to biodegradation. The synergetic effect of photocatalysis with the sulfate radical-based process was for the first time investigated. It was found that the studied artificial sweeteners were practically not susceptible to photolysis within 60 minutes of irradiation. In the presence of 2D titanium (IV) oxide, the artificial sweeteners were degraded entirely in less than 30 min, whereas the addition of peroxymonosulfate resulted in complete degradation after 10 – 15 minutes of the process.
