| 摘 要： | 本文作者发现草酸对钐、铕、铽和镝等离子均有荧光增敏效应,其绝对检测限分别达到0.79、0.02、0.018和0.70ppm。用标准曲线法测定了不产生熄(或(?))灭效应的钪、钇、镱和镥等重稀土混合氧化物中的铕、铽、镝含量,取得满意的结果。

| Abstract: | The optimum conditions and quenching of coexisting other rare carth ions for fluorometric determination of samarium,europium, terbium and dysprosium with oxalic acid have been investigated. The absolute detection limits are 0.79,0.02,0.018,0.70ppm,respectively. The contents of Eu_2O_3,Tb_4O_7, Dy_2O_3 in mixed heavy rare earth oxides was successfully determined by the standard curve methods. |
