Selection of Best pH Range for Extraction of Amine-Bromthymol Blue Complexes
This paper describes the determination of the best pH range for the extraction of amine-bromthymol blue complexes with chloroform. The experimental data on eight amine salts indicate that the best pH range is about 5.2-6.4 for a greater sensitivity in the analytical technique. A theoretical equation...

| description | This paper describes the determination of the best pH range for the extraction of amine-bromthymol blue complexes with chloroform. The experimental data on eight amine salts indicate that the best pH range is about 5.2-6.4 for a greater sensitivity in the analytical technique. A theoretical equation was derived and solved using a computer. The experimental results are in fairly good agreement with the theoretical results. |
