The effected of cations like Na+, K+, Cd2+, Cu-2+. Ag+, Zn2+, Co2+, Ni2+, Pb2+, Fe3+, Al3+ and Cr3+ on the fluorescence intensity of NMAA was studied. All the cations investigated with the exception of Na+ and K+ caused an enhancement in the fluorescence intensity of NMAA. Based on the florescence enhancement effect, these cations were divided into three groups. The fluorescence enhancement phenomenon was utilized for spectrofluorimetric determination of these cations in aqueous samples. Limit detection for each cation was also investigated and reported in this paper.
