ABSTRACT:
The use of a class of non-azo 1,8-naphthalimide dyes for the detection and quantitation of a paramagnetic metal cation in a non-aqueous medium and some of the dyes that will complex with a paramagnetic metal cation. The concentration of the paramagnetic metal cation is determined by monitoring differences in the detected fluorescent emission spectra of the non-azo 1,8-naphthalimide dye solution when it is mixed with paramagnetic metal cations present in the non-aqueous medium. The detected fluorescent emission spectra will vary in relation to the presence or amount of the paramagnetic metal cation in the mixture.
