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 μM. The detection limit of the sensor was calculated to be 15 nM
合成了一种新型的电活性化合物TCAC,其电化学聚合膜用于通过荧光/电化学双通道传感器检测2,4,6-三硝基甲苯(TNT)和2,4-二硝基甲苯(DNT)炸药。高灵敏度和选择性。特别地,对于TNT的分析该电化学传感器具有0.5μ增强的灵敏度中号。传感器的检测极限被计算为为15N中号。
