研究了二 - (2 -乙基己基 )二硫代磷酸 (D2 EHDTPA)从高氯酸介质中萃取钯的热力学 .通过考察二 - (2 -乙基己基 )二硫代磷酸浓度对 Pd( )的影响 ,测出了萃取反应的表观平衡常数 K、焓变ΔH、自由能变ΔG和熵变ΔS.
The thermodynamics of Pd (superscript 2 +) extraction from perchloric acid medium with di (2 - ethylhexyl) phosphorodithioic acid (D2 EHDTPA) The apparent equilibrium constant K, enthalpy change ΔH, free energy change ΔG and entropy change ΔS were determined.
