Resumen
A novel and simple method was developed for the preconcentration and determination of mercury(II) from hydrochloric acid solutions through their adsorption on Aliquat 336 (tri-octylmethylammonium chloride)-activated carbon. The determinations were made directly on the solid by X-ray fluorescence spectrometry, which had the advantage of eliminating the step of elution of the mercury retained.
This preconcentration system enabled the determination of Hg(II) in drinking water samples at µg l−1 levels. A 1700-fold enrichment factor was obtained. The described methodology showed excellent reproducibility, accuracy, and detection limits improvement by eliminating the step of elution of the analyte, replacing those methods based on cold vapor generation, reducing reagent consumption, and handling of samples.
