Optical and Electrochemical Selective Sensor for Zn2+ ions based on 4-(furan-2-ylmethyleneamino)-2,3-dimethyl-1-phenyl- 1,2-dihydropyrazol-5-one

摘要

A simple 4-(furan-2-ylmethyleneamino)-2,3-dimethyl-1-phenyl-1,2-dihydropyrazol-5-one (M1)2+ chemosensor was designed and positively applied for the selective recognition of Zn ions inmethanol. Sensing potential of chemosensor M1 with various metal ions was studied by the emission2+ and absorption spectra. The favorable coordination of chemosensor with Zn metal ion was initiatedby Job method. The binding constant and limit of detection (LOD) were calculated through titration2+methods. In DPV studies, chemosensor M1 also exhibits potential changes in the presence of Zn ions2+ that recognized complex behavior with Zn ions. Reported chemosensor could be applied for bare eyemetal sensing and real time sample analysis.
