Determinación de mercurio total mediante espectroscopia de absorción molecular UV/Vis: revisión de métodos

Máximo A. Gallignani, María del Rosario Brunetto Rodríguez de Cuinat, Carlos Daniel Ayala Montilla

Resumen


El mercurio es un elemento con características físicas y químicas particulares. Por ello, el Hg metálico y algunos de sus compuestos han tenido múltiples aplicaciones a lo largo del tiempo. Sin embargo, su elevada movilidad, persistencia y toxicidad exigen un estricto control en muchos productos, y en diferentes matrices. En consecuencia, se han desarrollado métodos basados en técnicas electroquímicas, espectroscópicas y cromatográficas. Este trabajo presenta una revisión crítica de metodologías basadas en la espectroscopia de absorción molecular UV/Vis para la determinación de mercurio total, fundamentadas en la formación de complejos. Se contrastan estrategias de trabajo, características generales y aplicaciones.
