为了改革沿用百余年的硫化氢系统分析法,我们曾研究出一套适用于完全分析的“常见阳离子分部分析法。这套方法能较紧密地结合元素周期系、将常见阳离子分为四个分析组,各组离子可按任意顺序自样品中以溶液状
In order to reform the systematic analysis of hydrogen sulfide, which has been in use for more than 100 years, we have developed a set of common cation partial analysis methods for complete analysis that combines elemental periodic systems more closely to classify common cations into four An analysis group, each group of ions in any order from the sample in solution
