| 摘 要： | 研究表明,除铕及镱外,用极谱法难以测定其它稀土元素。Laitinen等曾以0.1M氯化铵为支持电解质,在pH5～6下以经典极谱法测铕和镱,其半波电位分别为-0.671和-1.415伏。其后亦有人以氯化钙、氯化钾作底液,用经典极谱法测铕和镱。本文介绍以示波极

| Abstract: | For selection of appropriate supporting electrolyte in oscilloscopic polarographic determi-nation of europium and ytterbium, calcium chloride, potassium chloride and ammoium chloridewere compared, It was found that ammonium chloride solution is a suitable supporting electro-lyte for determination of europium and ytterbium and that the results obtained agree withthe requirement of ore analysis. |
