研究目的
To study the photochemical behavior of sulfamethoxazole from the kinetic aspect as well as the elucidation of the products arising from the solar irradiation of the antimicrobial sulfamethoxazole in the aqueous solutions.
研究成果
The study demonstrated that sulfamethoxazole undergoes several photochemical processes upon solar light excitation, including selective hydroxylation, photoscission of the S-N bond, a photo Fries process leading to an isomeric species, and a desulfonation process. These findings are important for understanding the environmental fate of sulfamethoxazole and its potential toxicity.
研究不足
The study focused on the photochemical degradation of sulfamethoxazole in aqueous solutions under controlled conditions, which may not fully represent environmental conditions. The formation of colored byproducts was noted, but their instability made elucidation difficult.
