| 内容記述 | The method for the spectrophotometric determination of ammonia by extracting the blue-colored indothymol with amyl alcohol, which is produced by the reaction of ammonia on thymol and chloramine T in an alkaline medium, has been examined. Fundamental properties such as the absorption characteristics, the amount of reagents to be added and the effect of heating time have been investigated and the optimum condition for the determination has been decided. The effect of diverse elements, especially of copper, cobalt and nickel has been investigated, and their allowable limit in the analysis of a steel has been given. The separation of ammonia from metals has also been studied. The results of analysis of carbon steel, chromium steel and manganese steel were satisfactory, being comparable with those obtained by the JIS method. | |||||||||||
