摘要：
We have synthesized a new Schiff base 1 having julolidine moiety, which detects Mn2+ and Fe2+ through naked eye in aqueous solution. The sensor 1 exhibited significant color changes from pale yellow to orange for Mn2+ and to dark green for Fe2+. The complex formations were proposed to be 1:1 ratio, based on Job plot and ESI-mass spectrometry analysis. The detection limits of Mn2+ and Fe2+ were found to be 7.11 mu M and 0.14 mu M, respectively, which are below the WHO acceptable limits (manganese: 7.28 mu M and iron: 536 mu M) in drinking water.
