Fluorescence Quenching, Aerosol OT Safranine T, Reverse Micelle.
Abstract
The fluorescence quenching of the dye, Safranine T (ST) by [Fe(CN)6]4-, [Fe(CN)6]3- and Fe2+ in reverse micellar medium of Aerosol OT (AOT) in heptane has been investigated. The ions influence the process to different extents. The process involves collisional quenching. Statistical model has been used to determine the radii of the trapped water in AOT reverse micelles (RM) using the dye as a probe.
