摘要:

The extraction was studied of complex of palladium with N-heterocyclic bases (2, 2′-dipyridyl, 1, 10-phenanthroline, 4, 7-dipb. enyl-1, 10-phenanthroline bathophenantroline). Complex compounds are quantitatively extracted by chloroform on the interval of concentrations of hydrogen ions: pH> 6.0 to 1.75 M HCl Dipy; pH> 3.5 to 5.0 M HCl – Phen; pH> 2.5 to 10 M HCl – BPhen. According to UV spectra, the composition of the extracted complex is PdAmCl2(Am=Dipy, Phen, BPhen).
