摘要: 本文研究了N,N二甲庚基乙酰胺(Ns03)从氯化物体系中萃取钯的机理。应用等摩尔系列法和斜率法确定萃合物组成为:(CH3CONR2H)2PdCl4。通过紫外-可见光谱法研究,证实N503萃取钯的机理属阴离子交换反应,其萃取方程式为:2CH3CONR2HCl(o)+PdCl42-(a)⇔(CH3CONR2H)2PdCl4(o)+2Cl-(a)。

Abstract: The extraction mechanism of palladium in chloride system by di(1-methyl heptyl)acetamide(N503)has been studied. The compsition of the extracted complex is(CH3CONR2H)2PdCl4 as determined by the equimolar series method and the slope method. Theextraction mechanism of palladium with N503 based on UV-vis spectra is proved to bean anion exchange reaction:2CH3-CONR2HCl0+PdCl42-a⇔(CH3CO-NR2H)2PdCl4(o)+2Cl-(a).
