SOLUBILIZATION OF DIPHENYLAMINE IN MICELLAR MEDIA

Seema Acharya and Renu Sharma*

ABSTRACT

The solubilization process finds extensive applications in industrial, pharmaceutical and biological field. Studies were made on the solubilization of diphenylamine in different concentrations of anionic, cationic and nonionic micellar media. The solubilization phenomenon has also been confirmed by absorption spectral studies. Spectral parameters like quantum yield, Stokes’ shift and molar extinction coefficient were calculated in micellar media at different concentration of compound. The changes in curve area and quantum yield has been indicated the change in solubilization pattern in presence of different class of surfactants. The maximum effect on solubilization of diphenylamine in its aqueous solution has been shown by non-ionic solvents.

Keywords: diphenylamine, solubilization, micellar media, spectral studies, non-ionic surfactant.
