中文摘要 | trinitrotoluene, usually known as tnt, is a kind of chemical explosive with hazardous and toxic effects on the environment and human health. ever-increasing needs for a secure society and green environment essentially require the detection of tnt with rapidity, high sensitivity and low cost. in this article, ionic liquid-graphene hybrid nanosheets (il-gns) have been used as an enhanced material for rapidly electrochemical detection of trinitrotoluene (tnt). il-gns were characterized by atomic force microscopy (afm), transmission electron microscopy (tem), x-ray photo-electron spectroscopy, electrochemical impedance spectroscopy, fourier transform infrared (ft-ir) spectroscopy and raman spectroscopy, which confirmed that il has been effectively functionalized on the surface of gns. significantly, il-gns modified glassy carbon electrode (gce) showed 6.2 and 51.4-folds higher current signals for tnt reduction than il-cnts/cce and bare cce, respectively. adsorptive stripping voltammetry (asv) for the detection of tnt on il-gns exhibited a good linear range from 0.03 to 1.5 ppm with a detection limit of 4 ppb on the basis of the signal-to-noise characteristics (s/n =3). moreover, il-gns/gce exhibited good stability and reproducibility for the detection of tnt. and, il-gns based electrochemical detection platform was also successfully demonstrated for the detection of tnt in ground water, tap water, and lake water with satisfactory results.
