TL;DR: In this paper, a simple, rapid, selective, and sensitive method for the spectrophotometric determination of trace amounts of mercury is developed based on the formation of the orange-red Hg(LAS)2 complex atpH 2.7.
Abstract: The complex equilibria of mercury(II) with Lawsone [2-hydroxy-1,4-naphthoquinone,LAS] were studied spectrophotometrically in 40% (ν/ν) ethanol water at 20°C and an ionic strength of 0.1M (NaClO4). A complete picture of the solution equilibria in thepH range 0.6–4.0 is presented. The complexation reactions were demonstrated and characterized using graphical logarithmic analysis of the absorbance graphs. A simple, rapid, selective, and sensitive method for the spectrophotometric determination of trace amounts of mercury is developed based on the formation of the orange-red Hg(LAS)2 complex atpH 2.7. The effect of interferences was studied. The method has been applied to the determination of traces of mercury in different matrices and some organomercury compounds.

TL;DR: In this paper, the reduction of aqueous solutions containing organomercury compounds by the hydrated electron has been studied by pulse and steady state radiolysis methods, and it was shown that the carbon-mercury bond is broken in the reduction process.
