Floatable graphitic carbon nitride/alginate beads for the photodegradation of organic pollutants under solar light irradiation / E. Falletta, M. Longhi, A. Di Michele, D.C. Boffito, C.L. Bianchi. - In: JOURNAL OF CLEANER PRODUCTION. - ISSN 0959-6526. - 371:(2022 Oct 15), pp. 133641.1-133641.13. [10.1016/j.jclepro.2022.133641]
Abstract:
Graphitic carbon nitride, both as powder and alginate floating beads, was synthesized by an easy and cheap
approach using two different precursors (melamine and urea) and properly characterized by several techniques.
The effect of the type of precursor on the photoactive properties of the final materials was investigated. Their
activity towards the photodegradation of different pollutants (dyes, drugs, and herbicides) both in ultrapure
water and simulated drinking water under solar light irradiation was investigated, reaching extraordinarily high
photodegradation results (99% for diclofenac and rhodamine B and 90% for isoproturon) compared to the
literature. The floating photocatalysts showed good stability during recycling maintaining high performances
after 5-time usage without post-treatment. Finally, liquid chromatography equipped with mass spectrometry
(UPLC/MS) was used to identify the main by-products formed during the photodegradation tests, and a plausible
transformation pathway has been proposed.
