云母单矿物的组成复杂,如沿用经典分析方法,消耗试样量多。本文采用闷罐溶样,以减少带入杂质元素,并采用吡啶沉淀分离法和纸上色层分离法,使用7毫克试样,一次完成18个项目的测定。纸上色层法将锂、钾、铷、铯分开,分别进行测定。同时我们发现,在测定锂的原点上还能分析钙、镁、锰。因此在一张纸上能取得7个元素分析数据。吡啶在 pH=6左右能定量沉淀铁、铝、钛、铌、钽、铍6个元素。铁在6N 盐酸中被甲基异丁基酮萃取进入有机
Mica single mineral composition is complex, such as the use of classical analytical methods, the amount of sample consumption and more. In this paper, bulk samples were dissolved to reduce the amount of impurity elements. Pyridine precipitation and paper chromatography were used to determine 18 items at a time using 7 mg samples. Paper color method Lithium, potassium, rubidium, cesium were separated, were measured. At the same time, we found that in the determination of the origin of lithium can also analyze calcium, magnesium, manganese. So on a piece of paper can get seven elemental analysis data. Pyridine at pH = 6 can quantitative precipitation of iron, aluminum, titanium, niobium, tantalum, beryllium 6 elements. Iron was extracted into 6N hydrochloric acid by methyl isobutyl ketone
