鹼金属钾、钠的微量测定,近来常用的是火焰光度法,而且火焰光度法也几乎是唯一的一种比较准确的方法,但是这种仪器设备目前还不算普遍,因此寻找其他比较简单的测定方法还是有必要的。 1948年,Fisher,Parsons和Morrison从氨基酸的纸上色层分离实验中,证明了一条非常重要的规律,即:“色层谱斑点面积与氨基酸溶液的原始浓度的对数成直线关系”。1949年,Brimley应用热传导和扩散的理论说明了这条规律。如果以S代表斑点面积,C代表未知物原始浓度,则得下列数学关系式:
Alkali metal potassium, sodium micro-determination, the recent commonly used flame photometry, and flame photometry is almost the only one more accurate method, but this equipment is not yet universal, so looking for other relatively simple Measurement method is still necessary. In 1948, Fisher, Parsons, and Morrison demonstrated a very important rule from the chromatographic separation of paper on amino acids: “The linear relationship between the chromatographic spot area and the logarithm of the original concentration of the amino acid solution”. In 1949, Brimley applied the theory of heat conduction and diffusion to illustrate this rule. If S on behalf of the spot area, C represents the original concentration of unknown, you have the following mathematical relationship:
