Oxidative and photochemical processes for the removal of galaxolide and tonalide from wastewater

Bioaccumulation and ecotoxicity increase during indirect photochemical transformation of polycyclic musk tonalide: A modeling study

“…5). This finding well explains the experimental facts that prolonged irradiation or ozonation bring no reduction of tonalide toxicity (Santiago-Morales et al, 2012). However, different results were obtained through the Habstraction pathways R abs C5 0 and R abs C3' (Figs.…”

“…Previous experiments showed that both tonalide and galaxolide are quite photochemically unstable (Buerge et al, 2003;Santiago-Morales et al, 2012), and the photodegradation rate of tonalide was approximately 12e30 times quicker than galaxolide under UV irradiation in laboratory (Buerge et al, 2003;Lucía Sanchez-Prado et al, 2004). This suggests that tonalide is more easily photo-transformed than galaxolide.…”

A review of solar and visible light active TiO2 photocatalysis for treating bacteria, cyanotoxins and contaminants of emerging concern

“…CECs come from a broad spectrum of sources such as but not limited to pharmaceuticals [90], steroids [91], antibiotics [92][93][94], phthalates [95], disinfectants [96], pesticides [97], fragrances (musk) [98,99], preservatives and additives [100]. From definition, the issue with CECs is that they are synthetic or naturally occurring chemicals but are not commonly monitored in the environment.…”

Efficient ozonation of reverse osmosis concentrates from petroleum refinery wastewater using composite metal oxide-loaded alumina

“…During the ozonation of catechol that is catalyzed by MgO/GAC, ÁOH was responsible for its degradation and mineralization, and this reaction rate constant was six times greater than single ozonation (Moussavi et al 2014). Catalysts containing Ce have also been studied for the ozonation of p-chlorobenzoic acid (Bing et al 2013), bezafibrate (Xu et al 2016), dimethyl phthalate (Yan et al 2013), and tonalide (Santiago-Morales et al 2012). However, their applicability for wastewater treatment has not yet been reported.…”
