Role of Nonionic Micelles of Tweens in Photovoltage Generation Using Fluorescein Dye

Abstract

Absorbance and fluorescence intensity of fluorescein decreases in the presence of aqueous nonionic micellar solution of Tween 20 (polyoxyethylene sorbitan monolaurate), Tween 40 (polyoxyethylene sorbitan monopalmitate), Tween 60 (polyoxyethylene sorbitan monostearate) and Tween 80 (polyoxyethylene sorbitan monooleate). Photovoltage generation using fluorescein dye in aqueous micellar solutions of Tweens (20, 40, 60 & 80) was studied using a photogalvanic cell. The characteristics of the cell were determined. An attempt has been made to analyze the results on a physicochemical basis.
