摘要
发现了钴在KSCN－H2SO4－As（Ⅲ）体系中的新的极谱催化波，对该催化渡性质作了初步研究．结果表明，该波为氢催化波，是Co2+与SCN－、H2AsO3-生成配合物催化氢的放电．该波用于矿样中微量钴的测定，结果满意．
This paper brings up a new cobalt polarographic catalytic wave in the solution of KSCN-H2SO4-As(Ⅲ), and does the primary research on the properties of its catalytic wave. The result shows that its catalytic wave to hydrogen is coordination compound of Co2+ SCN- and H2AsO3, catelyse hydrogen to discharge electricity. It is good to use this wave to measure trace cobalt in the mineral sample. The result is satisfying.
