seiler曾作阳离子三、四组,碱金属,卤素,各种磷酸根,以及铜、钴、镍、铀和镓的分离及检定。作者亦曾研究钛、锆、钍、钪、铌和铀的分离,吴孟炎曾作金、银、硒和碲的分离,均获良好效果。本文报告用反相两种方式研究铌和钽及贵金属的薄层层析行为。铌和钽及贵金属分离良好。铌和钽分离后经光谱检查铌中无钽,钽中无铌。此外,还比较铌、钽的薄层与纸层析。
Seiler has made three or four groups of cations, alkali metals, halogens, various phosphates, and the separation and verification of copper, cobalt, nickel, uranium and gallium. The authors have also studied the separation of titanium, zirconium, thorium, scandium, niobium and uranium. Wu Mengyan had good results in the separation of gold, silver, selenium and tellurium. In this paper, we study the thin-layer chromatography behavior of niobium, tantalum and precious metals in two ways. Niobium and tantalum and precious metals separated well. After the separation of niobium and tantalum, there is no tantalum in the visible spectrum of niobium and no niobium in the tantalum. In addition, comparison of thin layers and paper chromatography of niobium and tantalum is also carried out.
