THE DECOMPOSITION OF CARBON DIOXIDE BY Hg 6(3P1) AND Hg 6(3P0) ATOMS

Solution behavior of Hg ( II ) - cystamine by Uv - Vis and 199 Hg NMR

The combination of HgCl2 with the disulfide salt of 2-aminoethanethiol (cystamine dihydrogen dichloride) in water yields a two-dimensional chain {[HgCl4][(NH3CH2CH2S )2]}n (1). It consists of six-coordinate Hg in [HgCl4]n units with bridging and termainal Cl atoms. The disulfide groups, (NH3CH2CH2S )2 are held between the [HgCl4]n chain with weak S S interactions. The chlorides in the [HgCl4]n ...

Removal of Hg (I) and Hg (II) Ions from Aqueous Solutions, Using TiO2 Nanoparticles

For the first time, the present study removes ions of mercury, in the form of Hg (I) and Hg (II) ions, from aqueous solutions by adsorbing them onto titanium dioxide nanoparticles. The effects of various parameters, such as solution's initial pH, temperature, sorbent dosage, initial mercury concentration, and contact time have been examined on the adsorption process. The experimental results ha...

Oxidation of Hg(0) to Hg(II) by diverse anaerobic bacteria

Linear coordination of Hg(II) by cysteamine

Combination of the hydrochloride salt of cysteamine (1) with HgCl2 in water affords the unique compound, [Hg{S(CH2)2NH3}2](Cl)2 (2) in which the S Hg S angle is nearly linear. The ammonium portion of the molecule forms short hydrogen bonding contacts with the sulfur atoms. A related S···H bond is observed in the structure of the free ligand 1 indicating that such bonding does not require the pr...
