摘　　要：本文对自己合成的SGN树脂的富集测定贵金属条件,进行了详细研究。前文[1]发现在常温下树脂吸附Rh(Ⅲ)不完全。本文采用加热煮沸方法使Rh(Ⅲ)能定量吸附。光谱测定人工合成废液结果,回收率在72.72～111.2％之间,符合化学光谱测定要求。New SGN chelating resin containing aminoquanidine as functional group was synthesized. Optimum conditions for simultaneous concentrating traces of Au, Pd, Pt, Rh, Ir using this resin was investigated. Rh could be completely concentrated by boiling it with 0.15-0.20g resin for 2 h. The spectrographic determination of synthetic sample was satisfied with a recovery of 72.72-111.2%.
