Colorimetric detection of Cu2+ by amino phenol based chemosensor
A colorimetric chemosensor, based on 2-amino phenol Schiff base has been successfully synthesized by simple condensation reaction of 2-amino quinoline 3-carbaldehyde and 2-amino phenol. Synthesized Schiff base ligand 2-(2-aminoquinolin-3-yl methyleneamino) phenol (SBL) was characterised by various s...

| Summary: | A colorimetric chemosensor, based on 2-amino phenol Schiff base has been successfully synthesized by simple condensation reaction of 2-amino quinoline 3-carbaldehyde and 2-amino phenol. Synthesized Schiff base ligand 2-(2-aminoquinolin-3-yl methyleneamino) phenol (SBL) was characterised by various spectroscopic techniques. SBL displayed highly selective and sensitive Colorimetric enhancement to Cu2+ ion over 13 competing ions in ethanol–water (99:1/v:v) solution. UV titration experiment showed that SBL exclusively reacted with Cu2+ and the stoichiometric ratio is 1:1. The detection limit of SBL-Cu2+ was estimated to be 4.3 nM and 8.2 × 10–8 M, respectively. |
