Abstract We have prepared Schiff base functionalized 1,2,4-Triazole and Pyrene derivatives for selective, sensitive, and naked eye colorimetric detection of Cu2+ in the mixed organic- aqueous media. Amongst the 18 different metal ions studied for absorption and fluorescence titration, only Cu2+ ion encourages the modification in spectral properties of Schiff base functionalized 1,2,4-Triazole and Pyrene Probe. The stoichiometric ratio of the Probe-Cu2+ complex was determined to be 2:1 according to Job’s plot. The lower detection limit estimated for Cu2+ is 0.234 nM which shows excellent sensitivity and selectivity of the present analytical method towards detection of Cu2+ ion in the mixed organic-aqueous media. The present approach has been successfully utilized for the quantitative determination of Cu2+ ion from environmental aqueous solution.

Selective Sensor

A facile, highly selective colorimetric sensor based on 4-aminothiophenol (4-ATP) and Schiff base naphthalene-2-ol (L) modified silver nanoparticles (4-ATP-L-AgNPs) for detection of Fe(III) ion in aqueous solution. The presence of Fe(III) ion induced the aggregation of AgNPs that caused the red-shift from 430 to 440 nm, through a cooperative metal-ligand interaction from the coordination bond between Fe(III) ion and functional groups on AgNPs surface resulting in a colour change from dark brown to dark yellow with increasing absorption at 365 nm. The absorbance at 365 nm is linear with the concentration of Fe(III) ion ranging from 9.0 × 10-6 M to 9.0 × 10-3 M with a correlation coefficient of 0.9991. The detection limit of the developed method was 7.9 × 10-6 M. The practical application of 4-ATP-L-AgNPs for selective sensor for Fe(III) ion in various drinking water samples were demonstrated.
