Abstract
A highly selective hybrid way of TXRF determination of mercury(II) in drinking water at the level of n(10–2–100) μg/L is developed. The technique of preconcentration of mercury(II) ions includes directly suspended droplet microextraction with benzene in the form of an iodide molecular complex. The proposed method of determination is characterized by its high degree of sensitivity and reproducibility (cmin = 8 ng/L, sr = 0.12 (100 ng/L)). The accuracy of the analysis results is confirmed by the introduced–found method.
