Abstract:
The reagents of unsymmetrical carboxyazo group as coloring agents are often used in the spectrophotometric determination of calcium, barium and aluminum, but rarely used in that of iron. Dibromomethyl carboxyazo is a new coloring agent, and can be used in the determination of barium. It is not found that the agent is used in that of other elements.
