本文研究了阳极溶出法测定高纯锂、高纯钙中痕量铜。在丹麦 P04型极谱仪上配用旋转玻璃炭电极,当存在2×10~(-5)M Hg~(2+)而 pH=1.5～3.0时,在25毫升含0.10克高纯锂或0.50克高纯钙的试液中,分别在-0.15伏或-0.25伏处出现铜的良好的阳极溶出峰。选择予电解富集电位为-1.20伏,检出限可达0.1ppm。 In this paper, the determination of trace amounts of copper in high purity lithium and high purity calcium by anodic stripping method was studied. In the Danish P04-type polarography equipped with rotating glassy carbon electrode, when the presence of 2 × 10 -5 M Hg 2+ and pH = 1.5 to 3.0 in 25 ml containing 0.10 g of high-purity lithium or A good anodic dissolution peak for copper at -0.15 volts or -0.25 volts, respectively, was observed in a 0.50 gram sample of high purity calcium. Select to pre-electrolysis enrichment potential of -1.20 volts, the detection limit of up to 0.1ppm.
