Mixed oxidation of aqueous nonylphenol and triclosan by thermally activated persulfate: Reaction kinetics and formation of co-oligomerization products

Yumeng Qi et al.

Summary: This study investigated the mixed elimination of aqueous nonylphenol (NP) and triclosan (TCS) in a thermally activated persulfate system. It was found that the presence of TCS enhanced the conversion of NP, while NP hindered the degradation of TCS. A total of 23 intermediates were identified, with the dominant route being a single-electron coupling reaction induced by (OH)-O-center dot. These findings provide useful information for the elimination of mixed endocrine disrupting chemicals in water and wastewater.

Effective degradation of 2,4-dihydroxybenzophenone by zero-valent iron powder (Fe0)-activated persulfate in aqueous solution: Kinetic study, product identification and theoretical calculations

Mengting Zou et al.

Summary: In this study, 2,4-Dihydroxybenzophenone (BP-1) was efficiently degraded using the Fe-0/PS system, with various parameters affecting the degradation efficiency investigated. The degradation of BP-1 in different water matrices was compared, and multiple potential degradation pathways were proposed based on the identification of oxidation products. The study also showed a decrease in toxicity of intermediates during the oxidation of BP-1.

Products distribution and contribution of (de)chlorination, hydroxylation and coupling reactions to 2,4-dichlorophenol removal in seven oxidation systems

Xiaoxue Pan et al.

Summary: The transformation behavior of 2,4-dichlorophenol (24-DCP) was studied in seven different reaction systems, showing that complete removal of 24-DCP can be achieved in minutes in Fe(VI), KMnO4, NaClO, Fenton, and O-3 systems. LC-MS analysis identified 41 products, primarily hydroxyl substitution and coupling reactions. High chlorination was observed in the NaClO system, while coupling products accounted for about 45% of the removed 24-DCP under PS oxidation.
