一、有机层析剂的选择及层析剂各组分的作用对钽铌与伴生元素分离的纸上色谱上升层析法国内外常采用甲基异了酮、丁酮作有机层析剂,而且多选择氢氟酸介质层析。层析剂的选择是决定分离成败的关键问题。由于各种物质组成是复杂的,要找到一个在所有场合下都迁用的统一标准是困难的,但是
First, the choice of organic chromatography and the role of each component of the chromatographic separation of tantalum and niobium with associated elements by chromatography on paper chromatography often used methyl iso ketone, butanone as organic chromatography, and Multiple choice of hydrofluoric acid medium chromatography. The choice of chromatography is the key issue that determines the success or failure of separation. Due to the complexity of the various material compositions, it is difficult to find a uniform standard to be relocated on all occasions, but
