AbstractThe novel gel composite, based on the ground of ionic liquid (1-butyl-3-methylimidazolium hexafluorophosphate, BMIMPF6) 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 BMIMPF6-TiC gel modified electrode were studied in detail by scanning electron microscopy, energy dispersive X-ray spectroscopy, cyclic voltammetry, and differential pulse voltammetry methods. Due to the large specific surface area and strong adsorption property of TiC nanoparticles, as well as the good ionic conductivity and strong electrocatalytic property of BMIMPF6, the oxidation peak current of trp at BMIMPF6-TiC gel modified electrode showed good linear relation with its concentrations ranging from 0.50 to 30 mu mol/L and 30 to 500 mu mol/L, respectively. The detection limit was 0.053 mu mol/L. More importantly, the BMIMPF6-TiC gel modified electrode had good anti-interference ability and can be successfully applied in the electrochemical determination of trp in real food samples.
