广义地說,分析用的有机試剂应該包括所有在分析操作中使用的有机化合物——有机溶剂、指示剂(中和指示剂、吸附指示剂、氧化还原指示剂等),定量分析中所用的一部分基准物質、有机离子交換剂以及用以檢出各种离子的特殊有机試剂。本文只討論最后一种,也是平常所認为的有机試剂。这样的有机試剂能与某一或几个陽离子或陰离子在一定条件下生成具有一定的而且特殊外观(形态、顏色等)的沉淀,或發生特殊顏色变化(包括熒光的出现和消失),使我們从外观
Broadly speaking, the organic reagents for analysis should include all organic compounds used in the analytical operations - organic solvents, indicators (neutralization indicator, adsorption indicator, redox indicator, etc.) used in the quantitative analysis Part of the reference material, organic ion exchangers and special organic reagents to detect various ions. This article discusses only the last one, which is also commonly accepted as an organic reagent. Such an organic reagent can form precipitates with a certain and specific appearance (morphology, color, etc.) under certain conditions with one or several cations or anions, or undergo special color changes (including the appearance and disappearance of fluorescence) Make us look from the outside
