2018年3月1日 · In the present work advances and limitations in the application of Fe (III)-oxalate complexes (namely, [Fe (Ox) 3] 3-) to the photodegradation of a model persistent organic contaminant - 2,4-dichlorophenoxybutanoic acid (2,4-DB) in neutral aqueous solutions were systematically investigated for the first time.

Ferric oxalate, also known as iron (III) oxalate, refers to inorganic compounds with the formula Fe2(C2O4)3 (H 2 O) x but could also refer to salts of [Fe (C2O4)3]3-. Fe2(C2O4)3 (H 2 O) x are coordination polymers with varying degrees of hydration.

Efficiency of Fe (Ox) 3− system normalized to UVA absorption at the excitation wavelength is practically independent on [Fe (III)]. Thus, it is highly probable that concentrations of Fe (III) as low as < 10 −5 M could be applied in water treatment procedures using …

2018年3月1日 · Highlights • Advances and limitations of [Fe (Ox) 3] 3- complex as a photodegradation agent at neutral pH were found. • Optimal conditions for the photodegradation of persistent organic contaminant 2,4-DB were determined. • Fe (Ox) 33− system keeps high initial efficiency at low concentrations of both pollutant and the complex. •

2022年2月1日 · In this work, the photo reactivity of ferric oxalate (Fe (III)-Ox) complex in atmospheric particles was investigated. Raman spectroscopy was used to explore the mechanism and kinetics of Fe (III)-Ox photolysis occurring at the aqueous/gas interface, inside the …
