碳酸丙烯酯萃取金、铂的机理及其反萃过程的研究

THE EXTRACTION MECHANISMS OF Au AND Pt BY PROPYLENE CARBONATE AND THE PROCESS OF BACK-EXTRACTION

本文研究了PC-CHCl_(3)体系中,杂质金属离子对金、铂萃取的影响;金、铂反萃条件的选择.并用斜率法、饱和法、化学分析法、紫外光谱、红外光谱探讨了PC萃取金、铂的机理。

The effects of impurity ions on the extraction of gold and platinum in the propylene carbonate(PC)-chloroform system and the selection of back-extration condition have been investigated.The extraction mechanisms of gold and platinum were discussed with the slope method,the saturated method,chemical analysis,UV-spectrum and IR-spectrum.
