چکیده
In this work, two Schiff base ligands Z2a and Z2b derived from 5-aminoisophthalic acid were synthesized their structures characterized by FTIR, 1H(13C) NMR mass spectrometries. The compounds investigated for chemosensor properties towards metal ions [Na+, K+, Al3+, Cr3+, Mn2+, Fe3+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+ Pb2+] examined using colorimetric spectrophotometric methods (UV-Vis absorption florescence spectroscopy). Both showed similar sensing they have shown selective sensory Fe+3 Hg+2 ions. Moreover, the fluorimetric abilities nitroaromatic [4-nitrofenol (NP), nitrobenzene (NB), 2,4-dinitrofenol (DNP), 1,3,5-trinitrophenol (TNP)]. higher sensitivities DNP TNP than NP NB. Compound highest sensitivity with Ksv value of 2.4×104 M-1. Limit detections calculated both LOD values in micromolar levels. has lowest 2.77 M.
