摘要
本文研究了在H_3PO_4-NaH_2PO_4-HCl-NH_4Br-C_4H_6O_6介质中,用脂胺泡沫塑料分离富集Au^(3+)和Ag^+的条件试验,制定了题示方法,用于分析岩矿样品,获得了满意的结果。
After enrichment with esteramine foam, the method for determination of trace amounts ofgold and silver in H_3PO_4-NaH_2PO_4-HCl-NH_4Br-C_4H_6O_6 medium by platform graphite furnaceAAS is described in this paper. The analytical canditions have been studied. This method is usedto analysis rock mineral samples and got satisfactory results.
