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.
