| Popis: | Palladium(II) is efficiently extracted with (RS)-1-[2-(2,4-dichlorophenyl)pentyl]-1H-1,2,4-triazole from 0.2–5.0 M HNO3 solutions and can be selectively separated from Ni(II), Cu(II), Pb(II), Fe(III), and Ag(I) in the acidity range specified, as well as from lanthanides(III) in 2–4 M HNO3 solutions. The extraction of Pd(II) from 1 M HNO3 solution proceeds via coordination mechanism; this is an endothermic process in the 10–30°C temperature range. Palladium(II) is completely stripped with a nitric acid solution of thiourea or with 3–4 M NH4OH solution. |
