微量硒的示波极谱法快速测定

Rapid Test Microcontent Se in Oscillographic Polarographic Method

摘要: 硒的化合物SeOCl₂在约10mol/LHCl中能被C₆H₆萃取而快速地与许多共存元素分离, 然后在Na₂SO₃-NH₄OH底液中示波极谱法测定, 测定范围:0.00010%~0.20%硒, 结果良好。

Abstract: SeOCl₂ can be extracted by C₆H₆ and separated from other coexist elements in 10mol/L HCl, it also can be tested in Na₂SO₃-NH₄OH solution in oscillographic polarographic method, and has got good result, the test range of Se is:0.00010%~0.20%.
