Reduction of Mercury(II) by the carbon dioxide radical anion: a theoretical and experimental investigation
The laser flash photolysis technique (λexc = 266 nm) was used to investigate the mechanism of the HgCl2 reduction mediated by CO2·− radicals in the temperature range 291.7−308.0 K. For this purpose, the CO2·− radicals were generated by scavenging of sulfate radicals by formic acid. The absorbance of...
