γ-Irradiated Ni-hesperidin nanocomposite for selective trace-level sensing of sulfide ions
- 9 Downloads
In this article we report an environment friendly synthesis of Ni-hesperidin nanocomposites (NiNC). The synthesized NiNC were characterized using analytical techniques like absorption spectroscopy, transmission electron microscopy (TEM), dynamic light scattering (DLS), zeta potential (ξ potential), infra red spectroscopy, powder X-ray diffractometry and Raman spectroscopy. The same NiNC when synthesized in presence of γ-irradiation (gNiNC) showed selective spectral sensing of obnoxious sulfide anion amongst a set of 5 different sulfur based anions. The linear range of detection was found to be 7–85 μM. The mechanism of sensing was investigated using IR and Raman spectral analysis.
