研究了显色剂间羧基偶氮羧（ｍｅ－ｃ）与Ｂａ２＋的显色反应，在ｐＨ值为３．０的缓冲溶液中，Ｂａ２＋与间羧基偶氮羧（ｍｅ－ｃ）在λ＝７０５ｎｍ形成β型配合物，ε７０５＝１．２×１０５Ｌ／ｍｏｌ·ｃｍ．该显色反应可用于痕量Ｂａ２＋的分析，具有很高的灵敏性．
The color reaction between carboxyzocarboxylazine (me-c) and Ba2 + was studied. In the buffer solution with pH 3.0, Ba2 + and carboxylcarboxylazocine (me-c) The β-type complex was formed, and ε705 = 1.2 × 10 5 L / mol · cm. The color reaction can be used for trace Ba2 + analysis, with high sensitivity.
