Abstract:Previous studies mostly held that the oxidation capacity of ferrate depends on the involvement of intermediate iron species (i.e., Fe IV /Fe V ), however, the potential role of the metastable complex was disregarded in ferrate-based heterogeneous catalytic oxidation processes. Herein, we reported a complexationmediated electron transfer mechanism in the ferrihydrite−ferrate system toward sulfamethoxazole (SMX) degradation. A synergy between intermediate Fe IV /Fe V oxidation and the intramolecular electron tra… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
