Green speciation of iron using aqueous two-phase system
(Anais da Academia Brasileira de Ciências, 2019)
Development of method for the speciation of inorganic iron in wine samples
(2007)
In this paper, we proposed a procedure for the determination of iron(II) and total iron in wine samples employing molecular absorption spectrophotometry. The ligand used is 2-(5-bromo-2-pyridylazo)-5-(diethylamino)-phenol ...
Chelidamic Acid as a New Eluent for the Determination of Fe(II) and Fe(III) Species and Other Metals by High Performance Chelation Ion Chromatography
(Springer HeidelbergHeidelbergAlemanha, 2012)
Tailoring the stability and photo-Fenton activity of Fe-modified nanostructured silicates by tuning the metal speciation from different synthesis conditions
(Elsevier, 2018-11)
The stability and photo Fenton activity of nanoarchitectured silicates modified with Fe by the wet impregnation method were studied as a function of the used solvent, calcination temperature and iron loading. The physicochemical ...
Reactivity of catecholamine-driven Fenton reaction and its relationships with iron(III) speciation
(2015)
INTRODUCTION: Fenton reaction is the main source of free radicals in biological systems. The reactivity of this reaction can be modified by several factors, among these iron ligands are important. Catecholamine (dopamine, ...
Metal speciation of the Paraopeba river after the Brumadinho dam failure
(Elsevier B.V., 2021-02-25)
On January 25, 2019, a tailings dam at the Corrego do Feijao iron ore mine (Brumadinho, Minas Gerais, southern Brazil) ruptured and released similar to 12 million m(3) of mine tailings into the Paraopeba River, which is ...
Reagent-free flow-injection amperometric sensor for quantification and speciation of iron for bio-hydrometallurgical applications
(Elsevier Science Sa, 2015-12)
Iron ions are monitored in processes such as bio-leaching, bio-oxidation, ferric leaching, passivation control, and others. The role of iron in different hydrometallurgy processes is very important because it affects ...
Development of iron modified MCM-41 as promising nano-composites with specific magnetic behavior
(Elsevier Inc, 2015-02)
MCM-41 type mesoporous silica materials were synthesized and modified with different iron loadings by the wet impregnation method and exhaustively characterized by different instrumental techniques, including XRD, TEM, N2 ...
An overview of capillary electrophoresis in element speciation analysis of the environment
(Bentham Science Publishers, 2014-04)
This article focuses on the main developments in element speciation analysis by capillary electrophoresis (CE) since the 1990s. A brief description of the main techniques employed in CE analysis has been reviewed with ...
