A variety of techniques for the determination of heavy metal ions have been investigated intensively in the literature including spectroscopy, chromatography, electrophoresis, and fluorescence detection. Several are selective for both alkali and alkaline earth metals, such as lithium, sodium, potassium, zinc, calcium and magnesium, in which detection is necessary to monitor and regulate a number of cellular functions. Heavy metal cations such a lead and mercury have also been studied, due to their deleterious effects on biological system. In addition, there are several other environmental concerns were prepared by diazotization reaction. The molecular structures of azobenzene were analyzed by means of Fourier transform nuclear magnetic resonance, Fourier transform infrared spectroscop, field emission scanning electron microscope and UV-visible spectroscopy. Azobenzene based nanomaterials successfully detected Cs, Cu, Fe(II), Fe(III) and Sn ion. |
