Web1 mei 1986 · In the present paper we demonstrate that another important 'antioxidant' property of uric acid is the ability to form stable co-ordination complexes with iron ions. Formation of urate-Fe3+ complexes dramatically inhibits Fe3+-catalysed ascorbate oxidation, as well as lipid peroxidation in liposomes and rat liver microsomal fraction. Web10 apr. 2024 · These Ln-MOFs exhibit selective sensing of Fe3+ ions and Cr2O72− anions with better quenching constant values and lower detection limits. According to the tests, 3 and 4 show higher sensitivity and selectivity towards Fe3+ ions, but 2 reveals lower sensitivity and selectivity towards Fe3+ ions.
