泡沫塑料吸附原子吸收光谱法、氢醌滴定法及吸光光度法测定金

Determination of gold by AAS or hydroquinone volumetric titration or spectrophotometry after adsorption with poiyurethane foam

本文提出以泡沫塑料吸附金，对泡沫塑料处理后，可采用原子吸收光谱法、氢醌滴定法、分光光度法测定金。

In this paper,the gold are adsorbed on polyurethane foam.After treatment of the gold loaded polyurethune foam,the gold can be determined by AAS or hydroquinone volumetric titration or spectrophotometry, depending upon practical condition.
