Sensitive determination of manganese using flow injection and chemiluminescent detection

Abstract

The determination of Mn2+ in aqueous solution using a flow injection system and a chemiluminescent method of detection is reported. The Mn2+ ion is determined with high sensitivity and selectivity by exploiting the Mn2+ catalysis of the luminous oxidation of 7,7,8,8-tetracyanoquinodimethane by dissolved O2 in alkaline solution. This reaction is sensitized by Eosin Y, and further enhanced by means of didodecyldimethylammonium bromide bilayer vesicles. The limit of detection for this reagent scheme is 4.5 ppb. A reaction mechanism and energy level diagram for this system is also presented for the first time. The method is applied to the determination of Mn2+ in raw and processed water.
