本文成功地采用微分脉冲极谱法(DPP)同时测定矿石中的某些痕量金属离子。用酒石酸铵(0.1mol·L~(-1))作支持电解质:0.01％明胶作极大抑制剂。该样品产生8个十分明显的极谱峰。极谱图中的第1个信号E_p=0.08V(相对于SCE)可能是Ag~+或Au~(3+)引起的。为证实样品中存在Ag~+和/或Au请下载后查看，本文暂不支持在线获取查看简介。(3+),用EDTA作络合剂使单峰分裂成双峰:E_p=-0.04和-0.2V(相对于SCE),从而证实了样品中确实存在Ag~+和Au~(3+)。观测到的伏安结果与用AAS法测得的进行了比较。
In this paper, differential pulse polarography (DPP) has been used to simultaneously determine some trace metal ions in ore. Ammonium tartrate (0.1 mol·L -1) was used as the supporting electrolyte: 0.01% gelatin as a maximal inhibitor. The sample produced eight very polarographic peaks. The first signal in the polarogram E_p = 0.08V (relative to SCE) may be caused by Ag ~ + or Au ~ (3+). In order to confirm the presence of Ag ~ + and / or Au in the sample, please download it and view it later. This article does not support online access to view the introduction. (3+). Single peak was split into two peaks with EDTA as complexing agent: E_p = -0.04 and -0.2V (relative to SCE), confirming the existence of Ag ~ + and Au ~ (3+) in the sample. . The observed voltammetric results were compared with those measured by the AAS method.
