Abstract

We have synthesized a new Schiff base 1 having julolidine moiety, which detects Mn^{2 +} and Fe^{2 +} through naked eye in aqueous solution. The sensor 1 exhibited significant color changes from pale yellow to orange for Mn^{2 +} and to dark green for Fe^{2 +}. The complex formations were proposed to be 1:1 ratio, based on Job plot and ESI-mass spectrometry analysis. The detection limits of Mn^{2 +} and Fe ^{2 +} were found to be 7.11 μM and 0.14 μM, respectively, which are below the WHO acceptable limits (manganese: 7.28 μM and iron: 5.36 μM) in drinking water.
