ABSTRACT
Schiff base ligand of 4-amino antipyrine and 5-nitro 3-methoxy salicylaldehyde was prepared and characterized by analytical and spectral methods. UV-Vis and fluorescence spectral methods are used to investigate Schiff base ligand sensor ability towards metal ions. Change in colour of the Schiff base was observed with metal ions Al3+, Mn2+, Fe3+, Co2+, Ni2+, Cu2+ and Zn2+ visually. Schiff base exhibited emission band at 600 nm upon excitation at 560 nm in fluorescence studies. Quenching of fluorescence intensity was observed by addition of metal ions to ligand. Therefore, for metal ions detection the Schiff base ligand can be used.
