About

Marcos F.S. Teixeira is a prominent Brazilian analytical chemist whose research centers on the development and application of electrochemical sensors and flow-injection analysis systems. His major contributions lie in the design of innovative ion-selective electrodes for the determination of metal ions in complex matrices, particularly pharmaceuticals and environmental samples. His most cited work, "Flow-injection potentiometric determination of iron (III) in vitamin formulations using a tubular ion-selective electrode in oxalic medium" (1999, 4 citations), exemplifies his approach: constructing a graphite-epoxy electrode coated with an ion pair formed between [Fe(oxalate)₃]³⁻ and tricaprylylmethylammonium cation. This work demonstrated a robust, low-cost method for iron quantification in real samples, showcasing his ability to bridge fundamental electrochemistry with practical analytical applications. While his citation counts are modest, his sustained focus on sensor fabrication and flow-injection methodologies has contributed to the advancement of portable, efficient analytical tools. His research is particularly valuable for students and researchers interested in the intersection of materials science, electrochemistry, and pharmaceutical analysis, offering a model for developing selective, sensitive detection systems for trace metal analysis.
