摘要
A novel electro-active compound, TCAC, is synthesized and its electrochemical polymerized film is used to detect 2,4,6-trinitrotoluene (TNT) and 2,4-dinitrotoluene (DNT) explosives through a fluorometric/electrochemical dual-channel sensor with high sensitivity and selectivity. In particular, the electrochemical sensor for the analysis of TNT had an enhanced sensitivity of 0.5 mu M. The detection limit of the sensor was calculated to be 15 nM.
