| Popis: | A new chemosensor based on antipyrine derived Schiff's base (L) was synthesized by a reaction of antipyrene carboxaldehyde with 4-nitro phenylhydrazine. The probe L showed a color change toward Cu2+ from pale yellow to colorless. The detection limit of 0.42 μM for Cu2+ was below the World Health Organization (WHO) guideline for drinking water (31.5 μM). The probe L exhibits a 1:2 complex formation with Cu2+. The probe work in the pH range of 4-10 without interfering with competing ions. The probe was successfully applied to quantify Cu2+ in water and pharmaceutical samples. The binding mechanism of L with Cu2+ was characterized by using FTIR, mass and DFT analysis. Overall, probe L demonstrates a promising and potential for the detection of Cu2+ content in aqueous phase. |
