Consumption of H2S from Our Daily Diet:
Determination by a Simple Chemosensing Method
Posted on 2018-09-21 - 18:36
A unique
method has been developed for comparative analysis of
H2S produced from food samples from our daily diet, both
qualitatively and quantitatively. The selective detection of H2S has been executed by introducing a simple chemodosimeter
(PN-N3) that gives response on
the basis of intramolecular charge transfer. UV–vis, fluorimetric,
and NMR titrations were performed to demonstrate the sensing mechanism
and electronic environment of PN-N3 in the presence of H2S. Density functional theory
calculations were performed to validate the mechanism of azide (PN-N3) reduction to amine (PN-NH2) by the strong reducing power of H2S. The potentiality of this chemosensing method is that it
could be treated as a simple, less-time-consuming, and cost-effective
method for determining H2S in biological samples in the
nanomolar range.
