The solubilization of diphenyl diselenide in surfactant solutions

Abstract

Solubilization of diphenyl diselenide (DPDS) was studied in CTAB, OPE-10 and SDS surfactant solutions at 298 K. Solubility of DPDS increases with increase in the surfactant concentration due to its solubilization in micelles. UV-Vis, H¹ NMR and FT-IR spectroscopy was used to study the interaction, location of diphenyl diselenide in the micelle. The change in free energy for solubilization of DPDS in micellar media confirmed the favorable solubilizations in SDS, OPE-10 and CTAB solutions. The DPDS solubility was higher in OPE-10 and CTAB compared to SDS surfactant aqueous solutions.
