英文摘要 | 2,4,6-trinitrotoluene (tnt) is a widely used nitroaromatic explosive with significant detrimental effects on the environment and human health. its detection is of great importance. in this study, both electrochemiluminescence (ecl)-based detection of tnt through the formation of a tnt-amine complex and the detection of tnt through electrochemiluminescence resonance energy transfer (ecret) are developed for the first time. 3-aminopropyltriethoxysilane (aptes)-modified [ru(phen)(3)](2+) (phen=1,10-phenanthroline)-doped silica nanoparticles (rusinps) with uniform sizes of (73 +/- 3)nm were synthesized. tnt can interact with aptes-modified rusinps through charge transfer from electron-rich amines in the rusinps to the electron-deficient aromatic ring of tnt to form a red tnt-amine complex. the absorption spectrum of this complex overlaps with the ecl spectrum of the aptes-modified rusinps/triethylamine system. as a result, ecl signals of the aptes-modified rusinps/triethylamine system are turned off in the presence of tnt owing to resonance energy transfer from electrochemically excited rusinps to the tnt-amine complex. this ecret method has been successfully applied for the sensitive determination of tnt with a linear range from 1x10(-9) to 1x10(-6)m with a fast response time within 1min. the limit of detection is 0.3nm. the method exhibits good selectivity towards 2,4-dinitrotoluene, p-nitrotoluene, nitrobenzene, phenol, p-quinone, 8-hydroxyquinoline, p-phenylenediamine, k-3[fe(cn)(6)], fe3+, no3-, no2-, cr3+, fe2+, pb2+, so32-, formaldehyde, oxalate, proline, and glycine. |
