Electrochemical determination of tryptophan at room-temperature ionic liquid-titanium carbide nanoparticle gel modified electrode

Abstract: The novel gel composite, based on the ground o f i o n i c l i q u i d ( 1 -b u t y l -3 -m e t h y l i m i d a z o l i u m hexafluorophosphate, BMIMPF 6 ) and titanium carbide (TiC) nanoparticles, was used to modify glassy carbon electrode and applied to the electrochemical determination of tryptophan (trp). The physical and electrochemical characterizations of the BMIMPF 6 -TiC gel modified electrode were studied in detail by scanning electron microscopy, energy dispersive X-ray spectroscopy, cyclic voltamme… Show more

“…Neither too low nor too high pH is required to get the maximum electrochemical response of trp from the proposed electrode. 45 Finally, the time required for the insertion of trp and electrochemical response of trp from the MIP electrode was studied by observing the signal change from the time of addition to 5 min (Fig. S3).…”

“…GCEs can be easily modified by ionic liquids to increase their conductivity. 99,145,148,155,157,169,172,173,182,183 Yu et al, reported a voltammetric method for quantification of bisphenol A in real samples with good recovery. A detection limit of 8.3 × 10 −8 mol L −1 was obtained for the modified sensor (carbon ionic liquid electrode), 57 whereas in another study by Chen et al, a very low detection limit (1 × 10 −9 mol L −1 ) was achieved.…”
