TL;DR: In this article, a galvanostatic method has been employed to study the composition of adsorption layers which are formed on the surface of a mercury electrode, and the compositions of the adsorbed layers have been analyzed in terms of the cathodic charging curves (chronopotentiograms).

TL;DR: The galvanostatic method has been employed to study the interaction of diethylthallium cation with mercur metal as discussed by the authors, and it has been shown that "organic calomel", Et 2 Hg 2, is formed on the mercury surface, probably, via the formation of an intermediate diorganodimetallic cation, EtHgTl + Et

TL;DR: In this paper, the rates of exchange between organomercury compounds R 2 Hg mercury metal have been compared with the demercuration of the respective diorganodimercurials (k − 1 ) and with the interaction of R 2 hg with mercury (k 1 ).

TL;DR: The dominant fragmentation of organomercury compounds, namely the fission of the carbon-mercury bond, has been observed as mentioned in this paper, and the organic fragments formed either by direct fission or by extrusion of mercury fragmented in ways familiar from metal-free systems.
Abstract: The fragmentation, under electron impact, of eleven halogenated, aliphatic, and aromatic alkynylmercury compounds of general structure (XCC)2Hg has been examined. The dominant fragmentation of organomercury compounds, namely the fission of the carbon–mercury bond, has been observed. The organic fragments formed either by direct fission or by extrusion of mercury fragmented in ways familiar from metal-free systems; losses of C2H4, C2H2, and H2 were commonly seen, the proposed fragmentation pathways being supported by the observation of numerous metastable ions. Comparison of the relative metastable ion intensities suggests that the mercury extrusion products from the compounds with X = Et, Pr and But decompose through the same structures as are formed from the higher alkylbenzenes. Fragmentation of the organic portion competes effectively with mercury–carbon bond cleavage in the mass spectra of the compounds with X = But and p-MeOC6H4. The loss of HgCl2 from bis-(p-chlorophenylethynyl)mercury is also observed. In the mass spectrum of bis-(p-methoxyphenyl)mercury and bis-(4-phenylbutadiynyl)mercury metastable ion peaks were found corresponding to fragmentations from doubly charged parent ions to doubly charged daughter ions.

TL;DR: A method was developed for the routine identification and quantification of individual organomercury compounds at low concentrations in water and was shown to give good recoveries of methylmercury as methylMERcury iodide from water over the range 0.37–37 ppb of Hg.
Abstract: A method was developed for the routine identification and quantification of individual organomercury compounds at low concentrations in water. The method was shown to give good recoveries of methylmercury as methylmercury iodide from water over the range 0.37–37 ppb of Hg with a practical detection limit of 0.05 ppb of Hg. The method was not subject to interference from mercuric ion.
