| 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. |
