Abstract
The spectrophotometric studies of phenosafranin (PSF) dye in aqueous solutions containing three different types of surfactants such as CTAB (cationic), SLS (anionic), and Triton X-100 (neutral) show that PSF forms a 1:1 molecular complex with Triton X-100 and SLS, and there is no interaction of PSF with CTAB. The thermodynamic and spectrophotometric properties of these complexes suggest that PSF forms a strong charge-transfer complex with Triton X-100 whereas the interaction of PSF with SLS is coulombic in nature. The photogalvanic and photoconductivity effects in PSF-surfactants aqueous systems have been studied using platinum electrodes for both chambers, illuminated and dark, at room temperature (25°C); the PSF + Triton X-100 system only generates photovoltage and photoconductivity and it is almost reversible for a number of cycles.
