摘要
本文研究了N,N二甲庚基乙酰胺(N_(s03))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:(CH_3CONR_2H)_2PdCl_4。通过紫外-可见光谱法研究,证实N_(503)萃取钯的机理属阴离子交换反应,其萃取方程式为: 2CH_3CONR_2HCl_((o))+PdCl_4^(2-)(a)?(CH_3CONR_2H)_2PdCl_4(o)+2Cl^-(a)
The extraction mechanism of palladium in chloride system by di(1-methyl heptyl)acetamide (N_(503)) has been studied. The compsition of the extracted complex is (CH_3CONR_2H)_2PdCl_4 as determined by the equimolar series method and the slope method. Theextraction mechanism of palladium with N_(503) based on UV-vis spectra is proved to bean anion exchange reaction:2CH_3-CONR_2HCl_(0)+PdCl_4^(2-)_(a)?(CH_3CO-NR_2H)_2PdCl_(4(o))+2Cl^(-(a))
