Green and Efficient Determination of Iron(III) in Gasoline Using Microemulsion-Based Extraction and Digital Image Analysis.

ABSTRACT: Iron-(III) contamination in gasoline, originating from production or storage, compromises fuel quality and engine performance by catalyzing oxidation reactions, promoting gum and sediment formation, and accelerating engine wear. Accurate monitoring of this contaminant is, therefore, essential for ensuring fuel stability and extending engine lifespan. Conventional analytical methods, such as Atomic Absorption Spectroscopy, although highly reliable, demand sophisticated instrumentation and labor-intensive sample preparation. In this study, a sustainable and innovative approach is proposed by combining extraction induced by microemulsion breaking (EIMB) with digital image analysis (DIA) for the determination of iron in gasoline. Exploiting the ethanol naturally present in Brazilian gasoline,
