摘要：
The extraction of the ions of mercury (II) from dithiolphenolyate solutions in chloroform in the presence of hydrophobic amines. The optimal conditions for the extraction of mercury, pH(1/2) parameter, set the composition of extracted complexes. Hydrophobic amines used aniline, N-methylaniline and N, N-dimethylaniline. Among the test reagent has a better extraction capacity N, N-dimethylaniline. It has been found that associates formed in a weakly acidic medium (pH(opt) = 2,9-4,4). Highs in the light absorption spectra observed at lambda = 458-470 nm. The molar absorption coefficient was epsilon = (2,82-3,80).10(4).
