Oscillographic Titration with Sodium Tetraphenyl Boron for Pharmaceutical and Metallurgical Analyses |
| |
Abstract: | An oscillographic titrimetric method with sodium tetraphenyl boron is described for pharmaceutical and metallurgical analyses. Since the proposed method is based on the visual display of a sharp oscillographic end _ point and is not affected by the colors of the solution, precipitate and excipient, it can be employed to replace gravimetric analysis, non _ aqueous titration, and extraction-photometric analysis. The method is accurate, rapid, simple and cheap, and hence has large potential for extensive application. |
