【 摘 要 】
References(12)Cited-By(5)Distribution equilibria of mercury(II) between trioctylamine-hydrochloric acid salt in xylene and acidic solution containing high or low chloride ion concentrations were measured at 298 K. Mercury(II) is extracted as the complexes (RH)3HgCl5 ⋅H2O and (RH)HgCl3, which are formed respectively by the reactions of HgCl42- and HgCl3- with the amine salt, from aqueous solution with high chloride ion concentration. In the extraction from O.1 mol/dm3 hydrochloric acid solution, it is considered that HgCl2 also reacts with the amine salt and then forms the complex (RH)2HgCl4⋅H2O. The formation constants for their respective reactions were determined.
