Iranian researchers at Alzahra University in Tehran modified a glassy carbon electrode (GCE) with multi-walled carbon nanotubes (MWCNTs) to obtain an efficient catalyst for the oxidation reaction of sulfaguanidine (SG) as well as its detection within environmental samples.
Sulfonamides are commonly considered as pollutants of water, soil, agricultural crops and the ecosystem in general.
By exploiting the electrochemical behavior of the mentioned MWCNT-modified glassy carbon electrode, the members of the research team have come up with a novel nano-sensor for practical detection of the sulfonamides. Their innovative technique, in addition to being fast and simple, is comparatively cost-effective.
The MWCNT-modified glassy carbon electrode has indicated a higher sensitivity toward SG and serves as a more efficient electro-catalyst for oxidation of SG in comparison with a bare GCE. As another part of their study, the researchers have carried out a detailed cyclic voltammetry, along with other analyses, to evaluate the transfer coefficient, the heterogeneous rate constant and the diffusion coefficient for SG compound.
The research group reports on a convenient degree of precision and an excellent linear dynamic range featured in their method for the detection of SG. In addition, the results obtained from the analysis of SG in urine and serum samples have ascertained the applicability of the described technique for real sample analysis. Furthermore, the newly proposed method holds promise for wide acceptance as it does not involve the use of any costly instruments or analytical reagents.
An elaborate report covering more technical details of the research work has been published quite recently in the International Journal of Electrochemical Science.
