| Abstract: | Liquid-liquid extraction behavior of Pd(II) by the use 2-hydroxyl-4-sec-octyl- diphenylamine (abbreviated as H_2L) in trichloromethane has been investigated at 298.2 K. Under some conditions, the synergistic extraction behavior with 2-hydroxyl-4-sec-octyl- diphenylamine and trioctylphousphine oxide (TOPO) has also been studied. The slope analysis method shows that the composition of the extracted species are PdL and PdL(TOPO)_2. Equilibrium extraction constants and thermodynamic parameters were calculated. The results showed that increasing temperature is favorable to extraction of Pd(II) with 2-hydroxyl-4-sec-octyl- diphenylamine and more favourable to synergistic extraction with 2-hydroxyl-4-sec-octyl-diphenylamine and TOPO. |
