研究了在 HSGF2 54薄层板上 ,镝、镱与二甲酚橙形成的络合物的薄层色谱特性 ,展开剂为甲醇∶乙二醇 =2∶ 3( v/v)时 ,Rf 值为 0 .357与 0 .893,具有良好的选择性和重现性 .可用于单一化合物的定性检测
The thin layer chromatographic properties of the complexes formed by dysprosium, ytterbium and xylenol orange on HSGF2 54 were studied. When the developing agent is methanol: ethylene glycol = 2: 3 (v / v), the Rf value 0 .357 and 0 .893, with good selectivity and reproducibility. Can be used for qualitative detection of a single compound
