The monitoring of lead in the environment has gained importance because lead(II) ion is a toxic metal ion causing adverse environmental and health problems. In this paper, we reported the synthesis of 5,10,15,20-tetra(m-nitrophenyl)porphyrin as a sensing material aimed at the recognition of lead(II) ion. The synthesis and ion binding characteristics of the 5,10,15,20-tetra(m-nitrophenyl)porphyrin were investigated using FTIR, 1H NMR, and UV-Vis spectroscopy. The binding of lead(II) ion to the 5,10,15, 20-tetra(mnitrophenyl)porphyrin was found to give a new peak in the absorption spectra at 473.35 nm along with two isosbestic points at 483 nm and 465 nm, suggesting porphyrin complex formation of 5,10,15, 20-tetra(m-nitrophenyl)porphyrin-lead(II). The calculated limit of detection for lead(II) ion using 5,10,15, 20-tetra(m-nitrophenyl)porphyrin is 3.67 X 10–4 M and the association constant, Kass is 1.56 X 102 M–1. Herein, it was proposed that a new coordination compound was formed between lead(II) ion with 5,10,15, 20-tetra(mnitrophenyl)porphyrin through nitro group chromophore.
