【Abstract】 Liquid-liquid extraction behavior of Pd（II） by the use 2-hydroxyl-4-sec-octyl- diphenylamine （abbreviated as H₂L） 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.更多还原
