摘要
本文研究了N,N-二(1-甲庚基)乙酰胺(简称N503)从氯化物体系中萃取汞的性能,考察了各种因素对萃取平衡的影响,并应用斜率法及饱和法确定萃合物的组成为(CH_2CONR_2H)_2HgCl_4。其萃取汞的机理经紫外-可见光谱证实为离子缔合物萃取体系的阴离子交换反应。
The extraction behaviour of mercury from chlotide system with di(1-methy1-heptyl)acetamide(N503)has been investigated. The effects of the con-centration of H ̄+,NaCl, N503 on the extraction equillibrium have been obser- ved. By use of siope analysis and saturation capacity, the composition of ex- tracted complexes has been determined. The extraction mechanism of mercury with N503 byUV-Vis spectra is proved to be an anion exchange reaction.
