【摘要】 N₂₃₅萃淋树脂是胺类萃淋树脂.本文报道了该树脂在酸性体系中对金的静态分配比,讨论了温度、树脂用量、振摇时间对吸附金的影响,测定了树脂吸附金的饱和吸附容量及树脂的含氮量,由此确定萃合物的组成比,并用红外光谱探讨了该萃淋树脂吸附金的机理.更多还原

【Abstract】 N235 levextrel resin is a kind of amine levextrel resin. A synthesis is described for the preparation of N235 levextrel resin. The conditions of separation and enrichment for gold were investigated with a levextrel resin containing N235 as a fixed phase. The results show that N235 is a novel selective stationary phase for gold. The functional group capacity was determined by elemental analysis. The complex ratio of the resin to AuCl4- was 1: 1. The adsopption mechanism of this resin was also studied by IR Spectrometry.更多还原
